Question

If a electromagnetic wave has a frequency of 7.97e14 Hz, what is its wavelength? To what part of the spectrum does this wave belong?

Answer 1

`λ = "376 nm"` and it belongs to UV region

Explanation:

Wavelength`= c/f = (3 × 10^8 color(white)(.) "m/s") / (7.97 × 10^14 color(white)(.) "Hz") = 3.76 × 10^-7 "m" = "376 nm"`

It belongs to UV region
