MHT CET Physics question
A composite string is made up of two uniform strings having mass per unit length and . The string is under uniform surface tension. A transverse wave pulse , where y in mm, x is metres and t is in seconds, is sent through the lighter string towards joints, which is at , The equation of transmitted pulse is,
Answer: (C)
Solution
Speeds are and , so the transmitted amplitude is mm and the transmitted pulse keeps travelling along with the same
