Examine the wave diagrams shown below

Electromagnetic Wave	Mechanical Wave

Which of the following answers correctly explains how light waves and radio waves are different from all mechanical waves?

a.	Light waves and radio waves slow down in a vacuum. Mechanical waves speed up.
b.	Light and radio waves are always transverse waves, never longitudinal.
c.	Radio and light waves can propagate without a medium in a vacuum.
d.	Radio waves and light waves transmit energy but mechanical waves transmit matter

Stnd 07: Mechanical and Electromagnetic Waves
You are using a telescope to look up into the night sky, and you observe a blinking light from a satellite in orbit around the Earth.

What logical conclusion can you make about the properties of light from this observation?

a.	Light can travel through a vacuum. It can also travel through any medium.
b.	Light can travel through a vacuum. It can also travel through a gas.
c.	Light cannot travel through vacuums, but it can travel through solids, liquids, and gases
d.	Light travels at 186, 000 miles per second. It can travel through some mediums.

Stnd 07: Mechanical and Electromagnetic Waves
A ray of light shines through a transparent window. Next it shines through a transparent glass cup containing water and a straw in it. You notice that the straw in the water appears to be misshaped. The light shining through the glass next impacts a mirror on the far side of the room.
