Question

Wave motion? Yes or No?

1. A tire rolling around and round?

2. Ocean waves?

3. Sound?

4. Earth's orbit around the moon?

5. X-rays?

Answer 1

1. No
2. Yes
3. Yes
4. No
5. Yes

Answer 2

1.No
2. Yes
3. Yes
4. yes
//Yes because the wave nature of earth exists but it is very negligible
5. Yes

Answer 3

@shivam_bhalla: for number 4 are u sure? it is a simple harmonic motion, isn't it?

Answer 4

A simple harmonic motion means it is vibrating about its mean position.

Every matter has wave and particle nature as suggested by debroglie. But it matters which dominates. Sometimes wave nature dominates, and sometime particle nature.

In this case, particle nature dominates and the wave character is negligible but still present.
