Take this only if you can finish in 30 minutes I just want only answer not steps please answer these questions

Question 13 (1 point) In a ripple tank, a point on the second anti-nodal line from the centre is 15.0 cm 6 from one source and 30.0 cm from the other source. The sources are separated by -- 12.0 cm and vibrate in phase at 13.0 Hz. Calculate the wavelength of the wave. 9 22.5 cm 10.0 cm 12 -- 30.0 cm 15 7.50 cm 15.0 cm Question 14 (1 point) A water wave, travelling at 35 cm/s in shallow water, enters deep water. The angle between the incident wave front in the shallow water and the boundary between the shallow and deep regions is 440. The speed of the wave in the deep water is 24 cm/s. Find the angle of refraction in the deep water. O 20 440 GLGQuestion 12 (1 point) In a ripple tank, the wavelength X1 of waves in the deep water is 3.0 cm.
