Waves Review 2

Transparent, translucent, and opaque objects are determined by its ability to

• refract light

• diffract light

• increase its wavelength

• transmit light

Electromagnet waves

• consist of longitudinal waves

• consists of an electrical field and magnetic field

• travels only through matter

• travels only through a vacuum

What factor will affect diffraction?

• light bending through an opening

• light bending through a liquid from a gas

• light bouncing off objects

• light changing its medium

Refracted light is affected by

• reflected light

• wave speed

• a barrier or opening size

• wavelength

What is it called when white light separates into several colors of the rainbow?

• reflection

• diffraction

• refraction

• rarefaction

Why are we able to see opaque colors?

• the colors are being transmitted

• the colors are being reflected

• the colors are being diffracted

• the colors are being refracted

Amplitude is

• the height of a wave from the rest position to the crest or rest position to the trough

• the height of a wave from crest to trough

• the distance of a wave from crest to crest

• the distance of a wave from trough to trough

Ocean waves are

• longitudinal waves that travel in a parallel direction.

• transverse waves that travel in right angles.

• combination of longitudinal and transverse waves that travel in a circular motion.

• surface waves that travel in circular motion

The law of reflection states that the angle of incidence (light from the flashlight) equals to

• the angle of reflection

• the angle of refraction

• the angle of diffraction

• the angle of release

Waves carry

• energy and matter

• energy only

• matter only

• neither matter nor energy
