## How can you tell which wave has the most energy?

The energy in a wave is determined by two variables. One is amplitude, which is the distance from the rest position of a wave to the top or bottom. Large amplitude waves contain more energy. The other is frequency, which is the number of waves that pass by each second.

## What are the 7 electromagnetic waves in order?

This range is known as the electromagnetic spectrum. The EM spectrum is generally divided into seven regions, in order of decreasing wavelength and increasing energy and frequency. The common designations are: radio waves, microwaves, infrared (IR), visible light, ultraviolet (UV), X-rays and gamma rays.

## Which electromagnetic wave has the highest speed?

Electromagnetic spectrum

• Gamma rays have the highest frequency.
• Radio waves have the longest wavelength.
• None of those present has the highest speed. …
• Gamma ray photons have the highest energy.
• The exercise is about the constancy of the speed of light, independent of the energy of its constituent photons.

## Do waves lose energy as they travel?

As it travels, a sound wave’s energy is slowly lost as heat. This happens because the molecules of the medium through which it is travelling knock against each other as they transmit the sound wave energy. … Taking the example of a simple sine wave, if the barrier is wider than the wavelength, the wave will be absorbed.

## Why can’t humans see radio waves?

You can see visible light because the visible-light photons travel in small waves, and your eye is small. But because radio waves are big, your eye would need to be big to detect them. So while regular telescopes are a few inches or feet across, radio telescopes are much larger.

## Which type of wave travels the fastest?

P-waves and S-waves are body waves that propagate through the planet. P-waves travel 60% faster than S-waves on average because the interior of the Earth does not react the same way to both of them.

## Which has more energy radio or infrared?

Each photon contains a certain amount of energy. … Radio waves have photons with low energies, microwave photons have a little more energy than radio waves, infrared photons have still more, then visible, ultraviolet, X-rays, and, the most energetic of all, gamma-rays.

## Can electromagnetic waves harm you?

There is no doubt that short-term exposure to very high levels of electromagnetic fields can be harmful to health. … Despite extensive research, to date there is no evidence to conclude that exposure to low level electromagnetic fields is harmful to human health.

## Which is faster infrared or microwave?

Infrared rays are less controlled as compared to microwave radiation, which is more specified. The wavelength of infrared is shorter than that of microwave radiation, which falls in between radio waves and infrared on the electromagnetic spectrum. This means infrared rays have a higher frequency than microwaves.2 мая 2018 г.

## Is ultraviolet light faster than light?

Ultraviolet radiation has shorter waves than blue or violet light, and thus oscillates more rapidly and carries more energy per photon than visible light does. Light travels at a speed of 299,792 kilometers per second (about 186,282 miles per second).
