What material has the greatest velocity of light?
air
Explain why refractive index values of liquids are greater than one?
The velocity of light in a liquid sample is always less than the light in air The velocity of light in a liquid sample is always less than the light in air
Is the velocity of light higher in water or in air?
It's greater in air than in water.
When a ray of light from air enters to glass what happens to velocity?
it decreases
What is the velocity change when the ray of light passes from air to glass?
When a photon goes say from air to water, it slows down according to; n=c/v where n is refractive index of water c is velocity of light in air v is velocity of light in water It is stated that the frequency of the photon doesn't change when the photon enters the water. Only the wavelength changes.
Largest component of air?
The larges component of air - is Nitrogen (approximately 79 % by volume).
What can you say about the speed of differentcolors of light in the air?
they have the same velocity but have different wavelength and frequency
What happens to light when it travels from air into denser?
its frequency remains constant but velocity changes.
What happens to the velocity and wavelength of light when it passes from air into water?
The speed of the light decreases, and its wavelength increases by the same factor.
How many meters per second do light waves travel in air at a constant velocity?
3
Why sound travels in warm air than in cold air?
because density of air decreases with rise in temperature and velocity of light increases in wam ai
What is the velocity of light in meters?
the velocity of light is 300000000 m/s
