Here's the example that illustrate what you just asked. I will be using this example from astronomy. When you look up the sky to the stars, you are literally seeing into the past. The distance from you to the star you are looking at is x lightyears away. Lightyear is distance light travles in 1 year. So if a star is, say 100 lightyears away from you, then you are seeing the state of the star that much time ago.
Optical light waves are "Electromagnetic" waves. The colour seen is dependent on the wavelength of the light. Electromagnetic waves are transverse waves where the oscillation is 90 degrees to the direction of travel (unlike sound waves which are longitudinal).
Light waves originate from vibrating electrons.
visible light waves
Radio-waves, like light, are electromagnetic waves and hence travel at the speed of light.
Light waves are eletromagnetic waves and sound waves are mechanical waves. Additionally, a light wave is a transverse wave that does not require a medium through which to travel. Sound waves, on the other hand, are longitudinal waves where the source transfers the mechanical energy of the sound wave into the medium so it can travel.
Light waves
Visible light.
astronomy using radio waves, rather than visible light. visible light and radio waves are essentially the same, only radio waves have a much longer wavelength. not everything emits light in the visible band, many otherwise invisible objects can only be detected using extreme wavelengths.
The intensity of light waves is a measure of the energy that is carried by the waves. Light waves are electromagnetic waves.
Distomat is an instrument used to measure distance using light and radio waves.
Light is waves, propogated and emitted at the universal constant 'c'. The waves are created from energy in another form. Look up the (Lena) Hau lab work at Harvard and how the wave 'code' of light can be stopped (literally frozen) and started again.
When you listen to the radio, you are hearing sound, which has no resemblance to light, radio waves, or x-rays. However, the sounds you hear are created in the radio receiver, using information that was carried to your location by means of radio waves.
light is not composed of waves .it is a form of energy . i think the waves in light are not created because there is no reason for the creation of waves in light
Ultraviolet waves are smaller than light waves.
light waves are transversal, seismic waves are longitudinal.
No because light waves are stronger and brighter and sound waves are light and dull
Light waves do not emit radiation, light waves are radiation.
