Interactions of Waves

Scientists use electromagnetic waves to detect supernovas in space. Why are electromagnetic waves used instead of sound waves?

• Electromagnetic waves can travel in vacuums.

• Electromagnetic waves cannot be absorbed.

• Electromagnetic waves travel slower than sound waves.

• Electromagnetic waves are created by physical vibrations.

Light waves and sound waves are similar in that...

• They are both longitudinal waves

• They are both transverse waves

• They both transmit energy

• They both can travel through space.

When standing in the sun this behavior allows you to warm up as light and other waves hit your clothes. 

• Reflection

• Refraction

• Absorption

• Transmission
