Question

For any wave, the product of its frequency (f) and time period (T) equals 1. Look at the given options. Which pair of frequency and time period are not possible?

A. f = 5 units, T = 0.2 units
B. f = 6 units, T = 0.3 units
C. f = 0.5 units, T = 2 units
D. f = 4 units, T = 0.25 units

Answer 1
