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

• The sound waves will move faster through space and then slow down as it enters the Earth's atmosphere.

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

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

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.

What causes light waves to change directions when it travels through different mediums?

• The mediums have a different density causing the waves to travel at different speeds causing a change in direction.

• The mediums have a different volume causing the waves to travel at different speeds causing a change in direction.

• The mediums have a different color causing the waves to travel at different speeds causing a change in direction.

• The mediums have a different height causing the waves to travel at different speeds causing a change in direction.
