Answer 1
Reflection, this is incorrect because the rays are shown going through the glass, not reflecting. Mirrors are involved in reflecting. return to top

Answer 2
Refraction, this is correct because refraction is the bending of light rays, and here the light is being refracted into a focal point. return to top

Answer 3
Difraction is incorrect because diffraction is the spreading of light rays beyond a slit, not the bending of light rays through a lens as shown here. return to top

Answer 4
Polarization, this is incorrect because polarization is the filtering of light when the angle of light oscillation is perpendicular to the alignment of the filter. return to top
