MHT CET Physics question
A transverse wave of equation moves on a stretched string from one end to another end. In the equation of wave, x and y are in cm and t in second. The time taken by wave to reach from one end to another of string of length 45 cm is,
Answer: (C)
Solution
Wave speed (in the length unit per second, i.e. with x in metres), so \dfrac${0.45\
