NUMERICALS
1. The wavelength of waves produced on the surface of
water is 20 cm. If the wave velocity is 24 m s-1
calculate : (i) the number of waves produced in one
ro second, and (ii) the time in which one wave is
produced.

Answer 1

Answer:

F = 120 , T = 8.3 × 10³ s.

Explanation:

i) frequency or no. of waves produced per second

f = v/w

= 24 / 20

= 1.2

ii) time = 1/f

= 1 /1.2

= 0.83
