tah sun is our most important source of heat and light,without it living things cannoy survive on earth.

we get light and heat from other things ,too. the stars also give us heat and light.

can you name other sources of heat and light aside from the sun

Does refractionand reflection effect the wavelength of sound?

No, refraction and reflection do not affect the wavelength of sound. Wavelength is determined by the frequency of sound waves in a given medium, and it remains constant as sound waves interact through these processes. Refraction and reflection can alter the direction and intensity of sound waves, but not their wavelength.


Does the frequency change when a refraction occurs?

No, the frequency of a wave does not change when refraction occurs. Refraction only affects the speed and direction of the wave as it travels through different mediums, but the frequency remains constant.


Why frequency do not change in refraction?

Frequency of a wave does not change during refraction because frequency is determined by the source of the wave and is a characteristic property of the wave itself. Refraction only affects the speed and direction of the wave, but the frequency remains constant.


How does the index of refraction affect frequency?

The index of refraction does not affect the frequency of light. Frequency is determined by the source of the light and remains constant as light travels through different mediums with varying indexes of refraction. The only property that is affected by the index of refraction is the speed of light.


Which parameter of light doesnt change on reflection?

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.

Which property of light ray does not change in refraction?

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.

How does the frequency of light change as it passes through different mediums?

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.


On AM broadcasts what remains constant?

On AM broadcasts, the amplitude of the carrier wave remains constant. This means that the strength or power of the signal does not change, only the frequency of the signal is modulated to carry the audio information.


When a wave passes into a new medium what remains the same and what changes?

The frequency of the wave remains the same when passing into a new medium, while the wave's speed and wavelength may change. The wave may also experience reflection, refraction, and absorption as it interacts with the new medium.


What remains constant in simple harmonic motion if friction is ignored?

In simple harmonic motion, the frequency remains constant if friction is ignored.


In FM does the amplitude remains constant?

In frequency modulation (FM) the amplitude does not remain constant. Instead, the amplitude varies according to the modulation index and the frequency of the modulating signal. This is in contrast to amplitude modulation (AM), where the amplitude of the carrier signal is modulated while the frequency remains constant.
