As light travels, its wavelength can lengthen or shorten causing it to appear more red the further it travels or more blue if it has traveled a shorter distance. This effect, combined with various chemical spectral identifiers, can be used to determine the distance the light has traveled, giving a rough estimate to the location of its source.
changes in wavelength is called redshift(when wavelength is increased) and blueshift(when decreased). redshifts and blueshifts are attributable to the Doppler effect
Refraction is the bending of light as it travels from one medium to another with a different density, such as from air to water. This change in speed causes the light waves to change direction. Refraction happens because light travels at different speeds in different mediums, leading to a change in the angle of the light wave.
Nothing travels faster than light.
Light travels as light energy. Light is a type of electromagnetic wave.
Light travels in straight lines that we call rays.
The wavelength of light decreases as it travels from ice to water, due to the change in the speed of light as it crosses the boundary between the two mediums. This phenomenon is known as refraction.
light travels in ____________ which are called_
light travels very fast! it travels in the form of waves.
Light travels faster than sound
Light travels much faster than sound.

Light travels faster.
Nothing travels faster than light.
Light travels as light energy. Light is a type of electromagnetic wave.
The speed of light is dependent on the medium it travels through. Light travels fastest in a vacuum than in water or air.
Light travels at 299792458 meters per second in a vacuum.
Light travels an infinite distance until it is absorbed by an object.
1)Light travels in a straight direction.2)Light travels very fast with the speed of 300,000,000 meters per sec.3)Light travels in all directions.4)Light travels in vacuum(empty space).5)Light reflects.6)Light refracts.
