Light: Lenses Internet Scavenger Hunt WebQuest

A ______________ is a curved piece of glass or plastic designed to refract light in a specific way. Lenses are used in ______________ to help correct vision. They are used in ______________ to help view items that are far away and are used in microscopes to help view very small items.

• lens, glasses, telescopes

• mirror, glasses, telescopes

• lens, glasses, microscopes

• lens, contacts, cameras

Refraction is the bending of light as it passes through different media.

• The bending of light as it passes between different media

• The bouncing of light off surfaces

• The splitting of light into various wavelengths

• The absorption of light by an object

By using refraction, lenses can ____________ multiple light rays. Most of the lenses we use in everyday life are designed to bend light rays to a __________________________ where items will be in focus (clear).

• focus

• scatter

• diverge

• absorb

One way to classify lenses is by how they ______________________.

• function

• are shaped

• refract light

• magnify objects

A __________________________ will cause the light rays to bend to a specific focal point. Another name for this type of lens is a __________________________ lens.

• converging lens; convex

• diverging lens; concave

• converging lens; concave

• diverging lens; convex

Draw a converging lens below.

A __________________________ will cause light rays from a specific focal point to be spread out. Another name for this type of lens is a __________________ lens.

• diverging lens

• converging lens

• convex lens

• biconvex lens

Another way to classify lenses is by the __________________________ on each side of the lens. There are terms used to describe ______________ ______________. Then the two sides are combined to come up with the name of the lens.

• curvature

• magnification

• glass type

• aberration
