Given : a frequency of 8 x 10¹² Hz
To Find : wavelength (in meter)
Solution:
wave length * frequency = speed of light
wave length = ?
frequency = 8 x 10¹² Hz
speed of light = 3 * 10⁸ m /s
wave length * 8 x 10¹² = 3 * 10⁸
=> wave length = 3 * 10⁸ / ( 8 x 10¹²)
=> wave length = 30 * 10⁷ / ( 8 x 10¹²)
=> wave length = 3.75 * 10⁻⁵ m
wavelength = 3.75 * 10⁻⁵ m
