Shining ultraviolet light from an electrical plasma on to phosphors as found in a fluorescent lamp tube causes the outer electrons of the fluorescent powder to undergo quantum jumps to a higher energy level. When the electrons fall back to their original orbit they emit a single photon of light in the visible spectrum. This lowers it's frequency.
If you or the source of light is moving very fast Doppler shifts occur to raise or lower the light frequency depending on whether you are moving towards or away from the light source. This a conmmon technique used in astronomy to estimate speeds of moving objects.
UV light from the Sun hits the Earth's surface and is re radiated as infra red heat which is trapped in the Earth's atmosphere.The greenhouse effect.
When light travels from one media to another, its frequency remains the same because frequency is a fundamental property of the light wave itself and is determined by the source of the light. The speed and wavelength of light may change as it enters a new medium, but the frequency remains constant. This is described by the equation: frequency = speed of light / wavelength.
When light is reflected off a mirror, the frequency of the light does not change because reflection is a process that does not alter the properties of the light wave. The frequency of light corresponds to its color, and when we see our reflection in a mirror, we observe the same color that was emitted towards the mirror.
The frequency of electromagnetic energy traveling through a medium can change if the medium's refractive index changes. This can occur when light travels from one medium to another, causing a change in the speed of light, which in turn affects the frequency of the light waves.
No, the frequency of light does not change when it is reflected. Reflection is a process where light waves bounce off a surface, but the frequency remains constant. However, the direction and intensity of the reflected light may be altered.
Frequency is the parameter of light which doesnt change on reflection because it is the ratio of velocity of light in medium and wavelength of the particle.Hence,when velocity increases wavelength also increases and when velocity decreases wavelength also decreases but its ratio always remains constant.
The frequency of a light ray does not change when it undergoes refraction. The wavelength and speed of light can change, but the frequency remains constant. This is because frequency is a characteristic of the light source, not of the medium through which light is traveling.

The frequency of light corresponds to its color, and when we see our reflection in a mirror, we observe the same color that was emitted towards the mirror.
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
The frequency of electromagnetic energy traveling through a medium can change if the medium's refractive index changes. This can occur when light travels from one medium to another, causing a change in the speed of light, which in turn affects the frequency of the light waves.

The frequency of light remains constant as it passes through different mediums. However, the speed and wavelength of light may change, leading to effects like refraction and dispersion.
The frequency of light remains constant when passing from air to water. However, the speed of light changes due to the change in the medium, causing the wavelength to change. This change in wavelength results in the light bending or refracting at the interface between air and water.
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
The frequency of light remains constant as it changes medium from air to water. However, the speed and wavelength of light will change, causing it to bend or refract.
