4. calculate the wavelength of radiation with a frequency of 8.0 x 104 hz.

The wavelength of  wave is 0.375 × 10⁴ m.

Explanation:

Given data:

Wavelength of x-ray = ?

frequency of x-ray = 8×10⁴ Hz

Solution:

speed = Wavelength × frequency

Wavelength = speed /  frequency

c = 3 × 10⁸ m/s

λ= c / f

λ = 3 × 10⁸ m/s /8×10⁴ s⁻¹

λ = 0.375 × 10⁴ m

The wavelength of  wave is 0.375 × 10⁴ m.
