Question
An argon laser emits light at a wavelength of 489 nm (1 nm = 1 × 10-9 m). What is the frequency of this light?A6.13 x 1018 HzB6.13 x 105 HzC6.13 x 1016 HzD6.13 x 1014 Hz
Solution
To find the frequency of the light, we can use the formula for the speed of light:
c = λν
where: c = speed of light (~3.00 x 10^8 m/s) λ = wavelength ν = frequency
We are given the wavelength (λ) and need to find the frequency (ν). We can rearrange the formula to solve for ν:
ν = c / λ
Substituting the given values:
ν = (3.00 x 10^8 m/s) / (489 x 10^-9 m)
ν = 6.13 x 10^14 Hz
So, the correct answer is D6.13 x 10^14 Hz.
