Answer:
The wavelength of x-ray is 1 ×10⁻¹⁰ m.
Explanation:
Given data:
Frequency of xray = 3×10¹⁸ Hz
Wavelength of xray = ?
Solution:
Formula:
Speed of light = wavelength × frequency
c = λ × f
λ = c/f
This formula shows that both are inversely related to each other.
The speed of light is 3×10⁸ m/s
Frequency is taken in Hz.
It is the number of oscillations, wave of light make in one second.
Wavelength is designated as "λ" and it is the measured in meter. It is the distance between the two crust of two trough.
Now we will put the values in formula.
λ = 3×10⁸ m/s / 3×10¹⁸ Hz
Hz = s⁻¹
λ = 1 ×10⁻¹⁰ m
The wavelength of radiation is 1 ×10⁻¹⁰ m.
