Answer:
Frequency =0.67×10¹⁴ Hz
Explanation:
Given data:
Wavelength = 4461 nm
Frequency = ?
Solution:
Wavelength = 4461 nm /10⁹ = 4.461×10⁻⁶m
Formula:
speed of light = wavelength× frequency
speed of light = 3×10⁸ m/s
Now we will put the values in formula.
3×10⁸ m/s = 4.461×10⁻⁶m × frequency
Frequency = 3×10⁸ m/s / 4.461×10⁻⁶m
Frequency =0.67×10¹⁴ s⁻¹
s⁻¹ = Hz
Frequency =0.67×10¹⁴ Hz
