Question 3 of 12
3. Question
1 point(s)In a ripple tank experiment, waves are produced at the rate of 24 waves per second and the distance between 5 successive ripples is 20cm. The experiment is repeated by changing the frequency of the vibrator, and the new distance between 5 successive ripples is 12cm. What is the new frequency of the vibrator?

Question 10 of 12
10. Question
1 point(s)A water wave moves from a shallow region to a deeper region with the velocity of 25 cms-1 and 30 cms-1 respectively. What is the ratio of the wavelength in the shallow region to the wavelength in the deeper region?
CorrectIncorrect -
Question 11 of 12
11. Question
1 point(s)A vibrator produces plane water waves that travel at a velocity of 20 cms-1. When the waves enter a shallower region, the wavelength becomes 1.6 cm and the speed of the wave become 16 cms⁻¹. Determine the wavelength of the wave at the deeper region
