45. A sine wave of 15 kHz is changing at a faster rate than a sine wave with a frequency of ________.

(a) 25 kHz
(b) 12 kHz
(c) 18 kHz
(d) 1.3 MHz

Explanation
Explanation :

t = 1/f

Time is indirectly proportional to frequency. So, the lesser value of frequency from giving value will be of faster rate. So, 12 kHz is slower than the 15 kHz. Other rates are higher than the 15 kHz.
