Light

Everyday use of double convex lenses is:

• making larger images appear smaller

• creating upside-down images to help people with vision problems

• the only lens in a telescope

• making smaller images appear larger

Which of the following determines the color of an object?

• incidence of refraction of the material

• the wavelength of reflected light

• the wavelength of absorbed light

• speed of light in the medium

What is the correct order of the visible light spectrum?

• red, orange, violet, indigo, blue, green, yellow

• violet, blue, indigo, green, yellow, red, orange

• red, orange, yellow, green, blue, indigo, violet

• green, red, blue, orange, indigo, yellow, violet

How / Why does light change direction?

• Light bends in a curved path when its frequency is changed

• light changes direction when it is absorbed

• light changes direction when it speeds up or slows down through different mediums

• light changes direction when its wavelength is changed

A material that allows some light to pass through it is known as:

• Transparent

• Reflective

• Translucent

• Opaque

Mirrors work to create images through the process of:

• absorption

• reflection

• transmission

• refraction

This image shows

• A convex mirror

the light that is absorbed by an object will ____

• pass through the object without changing

• be reflected at the same angle

• change direction until it leaves the object

• raise the temperature of the object

An object that separates white light into the colors of the rainbow is called a:
