To solve the exercise it is necessary to take into account the concepts of wavelength as a function of speed.
From the definition we know that the wavelength is described under the equation,
Where,
c = Speed of light (vacuum)
f = frequency
Our values are,
Replacing we have,
<em>Therefore the wavelength of this wave is </em>
Answer:
Frequency of the light will be equal to
Explanation:
We have given wavelength of the light
Velocity of light is equal to
We have to find the frequency of light
We know that velocity is equal to , here
is wavelength and f is frequency of light
So frequency of light will be equal to
So frequency of the light will be equal to
