Question

Distance between crest and successive troughs 2.5 then what is the wavelength

Answer 1

Answer:

5 units

Explanation:

Distance between 2 consecutive Troughs or 2 consecutive Crests is equal to the wavelength. Here, the distance between 2 consecutive crest and trough is 2.5, hence it equal to half the wavelength.

Therefore, λ/2 = 2.5

Hence, λ = 5 units
