1. A rectangular piece of acrylic is placed in a tank of water. Blue light (7.5x1014Hz) travels from water to acrylic and then back into water. Calculate its speed and wavelength in each medium. Draw the light in its path from water to acrylic to water, showing the angles of reflection and refraction at each interface if a. it enters the acrylic making an angle of 60° with the water-acrylic interface (i.e. the angle is measured between the light ray and the surface). b.it enters the acrylic making an angle of 0° with the water-acrylic interface (i.e. the angle is measured between the light ray and the surface). water acrylic orange n=1.33 n=1.49 blue n=1.34 n=1.51
