What color has the highest frequency?

• violet

• red

• blue

• green

What part of the electromagnetic spectrum is given off by the sun?

• Only visible light

• Only UV light

• Visible light and Radio waves

• All of the electromagnetic spectrum

How does a prism affect the wavelengths of white light

• White light is bent and separated into different wavelengths

• White light is all turned into one different wavelength

• White light stays white

• None of the choices are correct

Why do some objects look black?

• Light never hits those objects

• They reflect all wavelengths of visible light

• They absorb all wavelengths of visible light

• They absorb every wavelength of visible light except they reflect black wavelengths

Why do things appear blue in the depths of the ocean?

• Blue light is the last light to disappear

• Blue light is absorbed by the ocean
