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 1014 HzB6.13 x 1018 HzC6.13 x 105 HzD6.13 x 1016 Hz
Solution
To find the frequency of the light, we can use the formula for the speed of light:
c = λν
where: c is the speed of light, which is approximately 3.00 x 10^8 m/s, λ is the wavelength, and ν is the frequency we're trying to find.
First, convert the wavelength from nm to m:
λ = 489 nm = 489 x 10^-9 m
Then, rearrange the formula to solve for ν:
ν = c / λ
Substitute the given values into the formula:
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 A6.13 x 10^14 Hz.
