Why does the lower part of the child appear so much different in size from the upper part?

• The light rays that travel through water and then into air are refracted.

What is happening in this picture?

• Reflection

• Refraction

Students often use a hand lens to make small objects appear larger. A hand lens makes objects appear larger because the lens-

• increases the light’s strength

• changes the color of the light

• bends light passing through it

• converts light energy to heat
