Physics: Light & Reflection

White light is actually light that can be separated into six elementary colors of the visible spectrum; which of the following is NOT one of them?

• blue

• yellow

• red

• green

• violet

X-rays, microwaves, and radio waves have many of the same properties as visible light.

• True

• False

Radio waves are part of the electromagnetic spectrum.

• Yes, they are

• No, they aren't

Light has been described as a/an__________, as a/an __________, and even as a/an __________ of the two.

• wave / vibration / fraction

• wave / particle / combination

• energy / reflection / diffusion

• particle / wave / neither

Light is considered to be a wave composed of oscillating electric and magnetic fields. Draw how the electric and magnetic fields are arranged as they move along.

What accounts for different colors?

• differences in colored filters and light strength

• differences in crest height and amplitude

• differences in frequency and energy

• differences in frequency and wavelength
