Solution
The wavelength (λ) of an electromagnetic wave can be calculated using the formula:
λ = c / f
where: c = speed of light in a vacuum = 3.00 x 10^8 m/s f = frequency of the wave = 1.82 x 10^18 Hz
Substituting the given values into the formula, we get:
λ = (3.00 x 10^8 m/s) / (1.82 x 10^18 Hz)
Solving this gives:
λ = 1.65 x 10^-10 m
So, the correct answer is D. 1.65 x 10^-10 m.
