Answer:
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.
