Answer:
Frequency = 0.8×10¹⁵ Hz
Explanation:
Given data:
Frequency of photon = ?
Wavelength of photon = 3.75 ×10⁻⁷ m
Solution:
Formula:
Speed of photon = wavelength × frequency
Frequency = speed of photon / wavelength
Now we will put the values in formula.
Frequency = 3 ×10⁸ m/s / 3.75 ×10⁻⁷ m
Frequency = 0.8×10¹⁵ s⁻¹
s⁻¹ = Hz
Frequency = 0.8×10¹⁵ Hz
