Answer:
The equatiom of kinetic energy is 1/2×m×v² where m represents mass and v is velocity :
The unit for kinetic energy is measured in Joules (J).
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
=
= x
= 35.385 x Hz (since 1
= 1 Hz)
= 35.385 GHz
