Properties of Microwaves in 1970:

  1. Metal surfaces reflect microwave rays.

  2. Both glass and plastic don’t stop them.

  3. They can traverse the atmosphere. As a result, information is transmitted back and forth from the satellite efficiently using microwaves. This explains why metal is used in satellite dishes, as metal reflects microwave radiation.

  4. A specific microwave frequency is absorbed by water. Food is cooked in microwaves using this capability. Microwaves heat it because food contains water, which absorbs the radiation. The water atoms and molecules in food begin to vibrate when heated. Consequently, the food’s temperature rises, and it becomes cooked.

  5. Wave effects impact microwave transmission, including reflection, refraction, dispersion, and interference.

  6. The quantity of heating depends on how long the substance is subjected to the radiation intensity.

  7. The conducting surfaces reflect the waves, which move straight ahead.

  8. Their wavelength of electromagnetic radiation is shorter.

  9. the ones with shorter wavelengths are most suited for radar systems used for aviation navigation.


Microwaves are 73 years old this year! Microwaves were unintentionally invented by inventor Percy Spencer in the 1940s while employed by the Raytheon Corporation. The original microwaves, the length of a contemporary American fridge-freezer, cost between £4,200 and £4,500. They were about 1.8 meters tall and weighed 340 kg. Quite different from the integrated, little models of today.

Microwave in the 1950s:

They didn’t truly take off until prices started to decline in the 1960s. According to statistics from Panasonic, 40,000 microwave ovens were marketed in the US in 1970, and 1 million by 1975. Due to the popularity of ready-meals in the UK, they also boomed in the 1970s; currently, 56% of us eat them.

The oldest microwave this year is 73 years old. While operating for the Raytheon Corporation in the 1940s, engineer Percy Spencer unintentionally discovered microwaves. The original microwaves were the length of an American-style refrigerator-freezer and cost between £4,200 and £4,500. They were roughly 1.8m tall and weighed 340kg.

Old Microwaves

Compared to modern microwave ovens, the original ones in history were enormous. An American defence company named Raytheon sold them for the first time in 1947. The RadaRange, as the device was referred to, was sold for $5000, or $51,000 in today’s dollars. These monstrosities produced a staggering 3000 Watts of electricity, stood about 6 feet tall, and weighed over one-third of a tonne.

These initial models, marketed for use in eateries, ship’s galleys, and big canteens, were unsuitable for residential use.
Domestic microwave ovens with counter-tops started to become widely accessible in 1967. They were offered for sale by the company Amana for US$495 ($3,408 in today’s currency).

The Modern Microwave

The short, wide design of the microwave we get used to seeing was developed by a company called Litton, which was well-known in the restaurant industry. Sales in the USA and Japan took off, going from tens of thousands by 1970 to millions by 1975. Microwaves became more practical and economical by the late 1970s because of technological advancements and lower-cost electronic components. One in four US households had a microwave in 1986. A startling 9 out of 10 American households reportedly had a microwave oven by 1997, according to the U.S. Bureau of Labor Statistics.

Most modern microwaves have the same height and wide box design that became common in the 1970s. However, you can purchase a variety of several types of microwave ovens. Sizes, colours, storage options, and power outputs vary. Some hang above the stove, some are integrated into kitchen cabinets, but some lie on the countertop. In addition to being able to microwave food, many modern microwave ovens also can grill, use convection heat, and even steam food.

Use your microwave oven for more than just reheating yesterday night’s pizza, no matter what kind you have. Remember to give thanks to Percy Spencer and his melting bar of chocolate after finishing a delicious dinner of microwave-slow-cooked lamb from decades ago.

Frequently Asked Question

Here are some frequent questions people may ask about How Much Were Microwaves In The '70s:

1. How Much Did a Microwave Cost In 1946?

It was in late 1946 when the Raytheon Company filed the patent. A Boston restaurant tested this large microwave, and the commercial version of the microwave first appeared in 1947 but cost about $ 5,000 each.

2. And How Much Did the First Microwave Cost?

In 1947 Raytheon introduced the world’s first microwave oven and named it Radarange, the winning name of an employee competition. The first microwave ovens were refrigerated and cost between $ 2,000 and $ 3,000. Between 195255, Tappan unveiled the first domestic model for $ 1,295.

3.Was the price of a microwave the same in 1975?

Between $ 189.95 to $ 439.95, microwaves were available. Since 1975, there has undoubtedly been significant dollar inflation. 100 dollars purchased in 1975 would now cost around $354 according to the changes in the consumer price index. Today, the price of the six-digit device is about $49.

4.People Also Ask How Much Did Microwaves Cost in the 1970s?

Raytheon, who bought the Amana company, introduced the first popular house model in 1967, the radar distance counter. It cost $ 495 (about $ 3,200 today). Consumer interest in microwave ovens has started to grow. In 1970, about 40,000 copies were sold in the United States.

5. Who Invented the Microwave in 1946?

Percy Spencer first invented the microwave.

7. How Much Did a Microwave Cost in 1980?

According to Litton, the average price of a microwave oven in 1980 was $ 425. While the price range is between $ 149 and $ 549, the average has dropped to around $ 280. Another type of consumer is buying microwaves, said James Freemont, director of marketing at Litton.

8. How Much Did a Microwave Cost in 1990?

And when the technology goes mainstream, of course, the price goes up too. In 1990, a much smaller microwave oven with two power levels could be purchased for the US $ 99.98, which is about US $ 183 today.

9. Is Microwave Radiation Harmful?

No, they are not harmful, but you don’t use metal and aluminium utensils as the waves come to your food, and it can damage your microwave.

10. What Were Microwaves Originally Used For?

Despite the potential of instant snacks, the first commercial microwaves in the radar range, introduced, were created by Raytheon in 1946 with the intention of usage in restaurants (as pictured above with a prototype called Raydarange) and for reheating meals on aeroplanes.

11. What Was Used Before the Microwave?

Frozen foods were cooked in water in a saucepan with a lid on a hot plate. Popcorn was made in a popcorn machine or the large Dutch oven on the stove. All the simple meals then known as TV were presented on aluminium trays.

13. Can Microwaves Cause Cancer?

Microwaves heat food. They do not affect foods not prepared with other cooking methods. So they don’t cause cancer. If you follow the instructions for using a microwave oven, there are no known harmful effects on humans.

14. When Did Microwaves Become Popular?

Microwaves became popular in 1967

15. How Much Does a Sharp Carousel Microwave Cost?

This microwave is a really big, glossy black with white back and interior and a weird 15-inch tempered glass top in a spacious 6 cubic foot interior. Most selected products and reviews.
