Calculate the wavelength (in nm)of the blue light emitted by a mercury lamp with a frequency of 6.88 × 10¹⁴ Hz. A) 229 nm B) 436 nm C) 206 nm D) 485 nm E) 675 nm

Question

Quizplus · Accepted Answer

The speed of light (c) can be calculated as c = λv, where λ is the wavelength and v is the frequency. Rearranging this equation, we can calculate the wavelength as λ = c/v.
Plugging in the given values, we have:
λ = c/v = (3.00 x 10^8 m/s) / (6.88 x 10^14 Hz) = 436 nm
Therefore, the wavelength of blue light emitted by the mercury lamp is 436 nm, which corresponds to choice B.
