Assessment: WAEC SSCE - Physics - 1995 (Objective) Subject: Physics

Question 1 Report

The period of a wave is 0.02 second. Calculate its wavelength if its speed is 330 ms^-1

6.6m

5.0m

4.0m

3.3m

2.0m

Answer Details

The relationship between the speed of a wave (v), its wavelength (λ) and its frequency (f) is given by the formula v = λf. The period of a wave (T) is the time taken for one complete oscillation or cycle. It is related to the frequency (f) by the equation T = 1/f. We can combine these two equations to obtain: v = λ/T We are given the period T = 0.02 s and the speed v = 330 m/s. Substituting these values into the equation, we get: λ = vT = 330 x 0.02 = 6.6 m Therefore, the wavelength of the wave is 6.6 m.
