Answer:
a) They have different wavelengths.
b) They have different frequencies.
Step-by-step explanation:
Electromagnetic waves (EM waves) refer to waves carrying electromagnetic radiant energy which are propagated through vacuum or non-vacuum (material medium). They range from radio waves to gamma rays; they travel through space at the speed of light (about 300 million metres per second) and they are measured in photons.
The EM waves have the following characteristics:
1. They have different wavelengths
2. They have different frequencies
3. They travel at the speed of light independent of the medium of propagation (vacuum or material medium)
4. They do not require a media to be propagated
<u>Based on the explanation above, Options </u><u>a</u><u> (They have different wavelengths) and </u><u>b</u><u> (They have different frequencies) are the correct answers</u>
The original volume of the shape was 250. You come up with this by multiplying all sides together. So, 5x5x10=250.
We do the same for the new shape, which now has a 7 in place of the 5. So 7x7x10=490.
Lastly, we subtract the volume of the new shape from the volume of the old shape to see the difference. So, 490-250=240.
So the answer to this is 240.
