Answer:
Frequency = 4.74 × 10¹⁴ Hz
Explanation:
Given data:
Wavelength of light = 633 nm (633 ×10⁻⁹ m)
Frequency of light = ?
Solution:
Speed of light = wavelength × frequency
Frequency = Speed of light / wavelength
Speed of light = 3 × 10⁸ m/s
Frequency = 3 × 10⁸ m/s / 633 ×10⁻⁹ m
Frequency = 0.00474 × 10¹⁷ s⁻¹
Frequency = 4.74 × 10¹⁴s⁻¹
s⁻¹ = Hz
Frequency = 4.74 × 10¹⁴ Hz
