Answer:
So then our answer would be:
D. 7.50 × 10¹⁴Hz
Explanation:
For this case we know the frequency for the blue light, given by the problem:
We can convert this into m like this:
We know that the speed of light is a constant and is given by:
And assuming that we have a fundamental wave, we need to satisfy the following basic relationship:
And if we solve for the frequency from the last formula we got:
Now if we replace the values given we have:
So then our answer would be:
D. 7.50 × 10¹⁴Hz
