=5 + 3 + 3 * 15
do multiplication first
=5 + 3 + 45
=8 + 45
=53
ANSWER: 53
Hope this helps! :)
We have been that frequency (y) varies inversely with wavelength (x).
We know that two inversely proportional quantities are in form
, where a is inversely proportional to b and k is constant of variation.
Our required equation would be
.
To find frequency of blue light, we will substitute
and
in our equation as:


Therefore, the frequency of blue light is 764.
Answer A is the only one that seems to make sense to me id choose A
Answer:
B is incorrect because you could set them equal to each other
