Light Waves

What would happen to light waves created when a star explodes (supernova) in space?

• The light waves will move slower through space and then speed up as it enters the Earth's atmosphere.

• The wavelength of the light waves wave would decrease as it travels through space and then it will increase as it moves into the Earth's atmosphere.

• The wavelength of the light wave would increase as it travels through space and then it will decrease as it moves into the Earth's atmosphere.

• The light waves will not travel through space because light must have a medium to travel through.
