Answer:
f = 1.87 × 10¹⁹ s⁻¹
Explanation:
Given data:
Wavelength of light = 1.6 ×10⁻¹¹ m
Frequency of light = ?
Solution:
Formula:
speed of light = wavelength × frequency
Frequency = speed of light / wavelength
speed of light = 3× 10⁸ m/s
Now we will put the values in formula:
Frequency = speed of light / wavelength
f = 3× 10⁸ m/s / 1.6 ×10⁻¹¹ m
f = 1.87 × 10¹⁹ s⁻¹
