Apologia Physical Science Module 15

Which has a higher frequency?

• Yellow light

• Green light

Which has the longer wavelength?

• ultraviolet

• radio waves

The speed of light in glass is 185,000,000 m/sec. If a particle is traveling through air at 200,000,000 m/sec, what will happen to the particle if it enters the glass?

• it will speed up

• it will slow down

The angle of reflection equals the angle of incidence is the definition of what term?

• radio waves

• converging lens

• the law of reflection

You want to concentrate light coming from a weak source by focusing it all on a single point. You will need to use a...

• converging lens

• diverging lens

When talking of mixing the colors of light, what will you get when combining blue and green?

• yellow

• magenta

• cyan

When mixing colors of light what will you get when mixing red and green?

• yellow

• magenta

• cyan

When mixing colors of light, what will you get when you mix red and blue?

• yellow

• magenta

• cyan

Describe light according to the current accepted theory. (Pick the long one!)

• Light in NOT a particle or a wave

• Light is a particle

• Light is a wave

• Light is made up of individual packets. Each packet is made up of two perpendicular transverse waves: one which consists of an oscillating electrical field and one that is made up of an oscillating magnetic field.
