C. It will move up and down, but it will return to about the same place.
A jellyfish is floating in the ocean. What will happen to the jellyfish when a wave passes through the water?
A. It will be carried away with the wave. B. It will not move, but the water around it will move. C. It will move up and down, but it will return |

|
The speed of light
In a vaccum, at what speed do electromagnetic waves move?
|
radiation
The transfer of energy as EM waves is called _______.
|
Reflects
A frog in white light appears green because it reflects/absorbs green light.

D. cold air
Through which of these media do sound waves travel most slowly?
A. iron B. wood C. water D. cold air |
B. Delta rays would have more energy than most gamma rays.
Imagine a scientist detects an EM wave, which he calls delta rays. The frequency of a delta ray is higher than that of a gamma ray. What can you infer about how fast the delta ray would travel?
A. Delta rays would travel faster than most gamma rays. B. |
