Frequency and energy of a wave

In summary, the higher the frequency of an electromagnetic wave, the more ability it has to penetrate bodies or cover larger distances due to an increase in energy. This can be seen in the example of UV rays penetrating the atmosphere, with UVC rays having the highest frequency and thus the most ability to penetrate. However, the extent to which this occurs depends on the properties of the target medium.

The higher the frequency of an electromagnetic wave,the more ability to penetrate bodies(or cover larger distances) as a result of increase in energy

What explains this?
Thanks

That is not exactly what they do see this thread https://www.physicsforums.com/showthread.php?t=526735

definately not what happens in the real world, not sure how you came about that description

cheers

It depends on the properties of the target medium. E.g. my sunglasses pass a lot of visible light through them, but not a lot of UV.

Btw, you picture indicates that lower frequency radiations penetrates further down into the atmosphere, not the other way round like you claimed in the OP.

UVC rays actually have higher frequency/photon energy (shorter wavelength) than UVB or UVA rays.

1. What is the relationship between frequency and energy of a wave?

The frequency of a wave and its energy are directly proportional. This means that as the frequency increases, the energy of the wave also increases. Conversely, as the frequency decreases, the energy of the wave decreases as well.

2. How does the frequency of a wave affect its wavelength?

The frequency of a wave is inversely proportional to its wavelength. This means that as the frequency increases, the wavelength decreases, and vice versa. This relationship is described by the formula: wavelength = speed of light / frequency.

3. How can the frequency of a wave be measured?

The frequency of a wave can be measured using a tool called a frequency counter or by counting the number of wave crests that pass a fixed point in a given amount of time. It is measured in units of Hertz (Hz).

4. What is the difference between high frequency and low frequency waves?

High frequency waves have a shorter wavelength and carry more energy than low frequency waves. They also vibrate at a faster rate and have a higher pitch. Low frequency waves, on the other hand, have a longer wavelength and carry less energy. They vibrate at a slower rate and have a lower pitch.

5. How does the frequency of a wave affect its behavior?

The frequency of a wave can affect its behavior in various ways. For instance, higher frequency waves are able to pass through certain materials, such as glass, while lower frequency waves may be reflected or absorbed by the material. Additionally, the frequency of a wave also determines its ability to cause resonance in objects, which can result in amplification of the wave's energy.
