MHT CET Physics question
A transverse wave in metre, is propagating along +ve X-axis on a string. A light insect starts crawling on the string with the velocity of at along the +ve X-axis from a point, where cm. After 5 s, the difference in the phase of its position is equal to
Answer: (D)
Solution
In 5 s the insect moves cm m, so the phase difference between its two positions is $k Δ
