 1 Waves made with a straight roller are shown crossing a ripple tank.

Draw rays starting with the three arrows shown.

2 Waves are shown crossing from deep to shallow water in a ripple tank.

a How do you know the two regions are of uiform depth?

b Which region has the shallow water?

c Draw the ray diagram.

d Mark and measure the angles of incidence and refraction. Record errors.

e Calculate the refractive index (n = sin i / sin r) with an error.

 

3 Waves are shown approaching three mirrors. Draw each wave after it has reflected from the mirror.
