the answer is in the picture ok
good luck don't worry it's a correct

Frequency and wavelength are two variables which are
indirectly proportional.
They are related in the following equation:
f = c / w
Where,
<span>f = frequency c =
speed of light w = wavelength</span>
Since c is constant, we can equate condition 1 and
condition 2:
f1 w1 = f2 w2
When w2 = 3 w1, then f2 becomes:
261.63 w1 = f2 (3 w1)
Cancelling w1:
f2 = 261.63 / 3
<span>f2 = 87.21 Hz</span>
Answer: I can conclude that the more direct light/rays a material receives, the more heat it absorbs. The results support my hypothesis because the results show that the temperature of the soil is highest at the 90º angle of insolation. At this angle, the soil sample received the most direct rays and absorbed the most heat.
