Answer 2

Step-by-step explanation:

question is -> A standing wave is produced on a string clamped at one end and free at the other. The length of the string

(a) must be an integral multiple of λ/4

(b) must be an integral multiple of λ/2

(c) must be an integral multiple of λ

(d) may be an integral multiple of λ/2.

A sanding wave is produced on a string fixed at one end and free at other end.

see figure, A wave of wavelength λ propagates at fixed where antinode is formed and node is formed at free end shown in figure.

we know,

length between consecutive antinode and node = wavelength/4 = length of string.

= λ/4 = l

hence, l = λ/4

hence, length is integral multiple of λ/4.
