the answer is c I hope this helps
Answer:
The frequency of infrared wave is 35.385 GHz
Explanation:
Given data:
Wavelength of infrared light = 8.45 mm = 8.45 x
m
Velocity of infrared light = 2.99 x
m/s
To find: frequency of the infrared wave = ?
We know that the wavelength and frequency are inversely proportional and the formula to derive frequency with velocity and wavelength is:
c = μλ, where
c is velocity of light
μ is frequency of light
λ is wavelength of light
Hence the frequency of light μ = c/λ
= ![\frac{2.99 x 10^{8} m/s }{8.45 x 10^{-3}m }](https://tex.z-dn.net/?f=%5Cfrac%7B2.99%20x%2010%5E%7B8%7D%20m%2Fs%20%7D%7B8.45%20x%2010%5E%7B-3%7Dm%20%7D)
=
x
![s^{-1}](https://tex.z-dn.net/?f=s%5E%7B-1%7D)
= 35.385 x
Hz (since 1
= 1 Hz)
= 35.385 GHz
The answer to this question would be A. Interference. This is because when two sounds with slightly different frequencies creates a periodic variation in volume.

Answer:
A comet
Explanation:
The picture is of an elliptical orbit of a comet. You can tell it is a comet because of the tail. Also, I just took the test and it was a comet.
