The Doppler Effect. As light travels from distant stars, it loses energy. its wavelength turns into a lesser amplitude (the height of a wave), which turns from ultraviolet, to infrared, which is red. Thus, Redshifting.
light travels from sun to earth through vaccum, so its easily understood
Nothing that we know of.
light travels in ____________ which are called_
Light always travels in a straight line with respect to space-time. If it appears to the observer that the light beam has bent it can only be concluded that space-time is bent.
Its speed has been measured accurately, using lasers.
It's an intrinsic property - or in other words, we don't know. It just does.
light travels very fast! it travels in the form of waves.
during lightening we will experience the light first and sound later. it is the good proof.
Light travels faster.
Nothing travels faster than light.
Light travels as light energy. Light is a type of electromagnetic wave.
Light actually travels in waves.This is known to be true because there are only 3 ways that energy can be transferred. As you probably already know, light does not need a medium to travel through because it travels through space. Electromagnetic waves are the only form of energy transfer that do not require a medium to travel through.
