<p>A practical method for demonstrating refraction is to shine a light through a glass of water. You will see that the light beam changes directions as it passes from the air to the water. This is because light travels at different speeds in air and water.</p> Signup and view all the answers

<p>Because each color is refracted differently, each bends at a different angle, resulting in a fanning out and separation of white light into the colors of the spectrum</p> Signup and view all the answers

<p>Position your white light source above or around the prism to point towards one of its faces. Turn on the light and observe how the beam refracts off each face as it passes through, dispersing into its component colors.</p> Signup and view all the answers

Height of a wave

The distance between two corresponding parts of a wave

The time required to complete one cycle of a wave

1. speed=distance/time; 2. speed=frequency x wavelength

The number of waves that pass a given point per second

Waves carry energy from one place to another

Light that passes through matter

Light taken in by an object

Light that is bounced off the surface of an object

Light deflected from a straight path

1. medical diagnosis; 2. automatic door openers; 3. animal communication; 4. sonar

An area where P+S waves cannot be detected

Particles move perpendicular to wave direction

Particles move in the same direction as the wave

Water waves and S waves (a type of seismic wave)

Sound, Ultrasound, and Shock Waves

Each color refracts differently, bending at different angles

Position light source so it hits a prism, observe refraction

The angle between the incident ray and the normal

The ray that comes from an object and strikes a surface

The light ray that bounces off a surface

An imaginary line perpendicular to the surface at the point of incidence

The angle that light bounces off the surface

The angle of incidence that produces an angle of refraction of 90 degrees

When light hits the boundary at an angle greater than the critical angle

A measure of how much light bends when entering a new medium

Features like amplitude, wavelength, and frequency that define waves

Waves produced by earthquakes that travel through the Earth

The way sound travels through different mediums
