Answer:

90 cm. B.

45 cm. MEDIUM. Answer. The distance between two successive compression or rarefaction is the wavelength (λ). So the distance between compression and subsequent rarefaction will be λ/2. Thus, the 1st compression and 5 th rarefaction =4λ+λ/2=29λ=4. 5(20)=90cm as (λ=20cm) Answer By Toppr. ASK.
