What happens to the wave when you decrease the wavelength or increase the wavelength?
When you decrease the wavelength of a wave, its frequency and energy increase. This is known as blue shift and is common in light waves. Conversely, when you increase the wavelength of a wave, its frequency and energy decrease. This is known as red shift and is also observed in light waves.
What happens to the energy of light waves if frequency increases?
If the frequency of light waves increases, the energy of the waves also increases. The energy of a photon is directly proportional to its frequency, according to the equation E=hf, where E is energy, h is the Planck constant, and f is frequency. Therefore, higher frequency light waves have higher energy content.
2 What happens to light when it falls upon a material that has a natural frequency equal to the frequency of the light?
When light falls on a material with a natural frequency equal to its own, resonance occurs. This causes an increase in the amplitude of the vibrations in the material, resulting in the absorption of more energy. As a result, the material may heat up or other effects may be observed, depending on the specific properties of the material.
How does an increase in the intensity affect the maximum kinetic energy of the photoelectrons?
An increase in the intensity of light does not affect the maximum kinetic energy of photoelectrons. The maximum kinetic energy of photoelectrons is determined by the frequency of the incident light, according to the photoelectric effect equation E = hf - φ, where f is the frequency of the light and φ is the work function of the material.
What happens as the frequency of photons increases?
For electromagnetic radiation,c = speed of light = 3.0 x 108 m/s = frequency x wavelengthAs the frequency of light waves increase, the wavelength decreases. For electromagnetic radiation, the wavelength times the frequency equals the speed of light, c, which is 3.0 x 108 m/s. So, if the frequency increases, the wavelength will decrease, and if the wavelength increases, the frequency decreases.

What happens to the energy that light gains from a Gravity Assist when passing by a mass in space since light cannot increase in speed?
Light cannot increase its speed, but it can increase its energy. Doing so will increase its frequency, or equivalently shorten its wavelength. It will thus be blue shifted.

If the frequency of light waves increases, the energy of the waves also increases. The energy of a photon is directly proportional to its frequency, according to the equation E=hf, where E is energy, h is the Planck constant, and f is frequency.

So, if the frequency increases, the wavelength will decrease, and if the wavelength increases, the frequency decreases.
What happens when light has higher frequency?
When light has a higher frequency, it means the wavelength is shorter and the energy of the light is higher. Higher frequency light can have more pronounced effects, such as greater potential for damaging biological tissues and the ability to excite electrons to higher energy levels. Examples of high frequency light include ultraviolet and X-rays.
What is the relationship between frequency and energy of a light wave?
The frequency of a light wave is directly proportional to its energy. This means that as the frequency of a light wave increases, its energy also increases. In other words, light waves with higher frequencies have higher energy levels.
If the frequency of light is cut in half what will happen to the energy?
The energy of the light is directly proportional to its frequency according to the equation E=hf, where E is energy, h is Planck's constant, and f is frequency. Therefore, if the frequency of light is cut in half, the energy of the light will also be halved.
Does kinetic energy of photo electron depend upon intensity of light?
No, the kinetic energy of a photoelectron is primarily determined by the frequency of the incident light (photon energy), not the intensity of the light. Increasing the intensity of light will increase the number of photoelectrons emitted but will not change their individual kinetic energies.
What do radiant energy decreases or increases with?
Radiant energy increases with an increase in temperature or intensity of a light source. It decreases as it moves further away from the source due to scattering, absorption, and reflection by the medium through which it travels.
What characteristic determines the energy of a light wave?
It's wavelength or frequency. The energy of a light photon (particle of light) is equal to (h x c) / wavelength, or to h x frequency, where h is Planck's constant and c is the velocity of light in a vacuum.
