Answer :
Answer:
ν = 4.67x10¹⁴ Hz.
Explanation:
The frequency (ν) can be calculated using the following equation:
[tex] \nu = \frac{c}{\lambda} [/tex]
Where:
λ: is the wavelength = 642x10⁻⁹ m
c: is the speed of light = 3.00x10⁸ m/s
[tex] \nu = \frac{3 \cdot 10^{8} m/s}{642 \cdot 10^{-9} m} = 4.67 \cdot 10^{14} s^{-1} = 4.67 \cdot 10^{14} Hz [/tex]
Therefore, the frequency of the light is 4.67x10¹⁴ Hz.
I hope it helps you!
Answer:
Explanation:
Frequency, f = c/λ
Where,
Wavelength, λ = 642 nm
= 6.42 × 10^-7 m
Speed of light in air, c = 3 × 10^8 m/s
f = 3 × 10^8/6.42 × 10^-7
= 4.65 × 10^14 Hz.
