Answer:
Wavelength = 0.4×10⁻⁶ m
Explanation:
Given data:
Wavelength of light = ?
Frequency of light = 7.66 × 10¹⁴ Hz
Solution:
Formula:
speed of light = wavelength × frequency
Wavelength = speed of light / frequency
Wavelength = 3×10⁸ m/s / 7.66 × 10¹⁴ Hz
Hz = s⁻¹
Wavelength = 3×10⁸ m/s / 7.66 × 10¹⁴s⁻¹
Wavelength = 0.4×10⁻⁶ m
