in glass speed slower, poss 2/3 that of vacuum
Light has wavelength 600 nm in a vacuum ,the frequency of the light is 2 ×[tex]10^{-13}[/tex] Hz.
The separation between such a wave motion's crests and troughs would be known as the wavelength of photons.
The total number of waves that pass a specific location in a predetermined amount of time is known as frequency.
Calculation of frequency
Given data:
wavelength = 600 nm = 600 × [tex]10^{-9}[/tex]m
index of refraction = 1.5.
Frequency can be calculated by using the formula:
v = f × wavelength
f = wavelength / v
Where, f = Frequency , v is velocity.
put the given data in above equation.
f = wavelength / v
f = 600 × [tex]10^{-9}[/tex]m / 3 × [tex]10^{8}[/tex]
f = 200 × [tex]10^{-15}[/tex].
f = 2 ×[tex]10^{-13}[/tex]
Therefore, the frequency of the light is 2 ×[tex]10^{-13}[/tex] Hz.
