A wave is a disturbance that transfers __________ from place to place, without carrying matter. 100 Points

Energy 100 Points

Identify the wave with the lowest frequency and lowest amplitude: 200 Points

Wave D 200 Points

This phenomenon occurs when a wave changes speed as it moves from one medium to the next. 300 Points

Refraction 300 Points

On the diagram below, label the following parts: Incident Ray Reflected Ray Angle of incidence Angle of reflection Normal 400 Points

Incident Ray Reflected Ray 400 Points

Show with your hands and explain the difference between a transverse and longitudinal wave, showing the following: Compression Rarefaction Crest Trough Normal 500 Points

A transverse wave moves up and down or side to side. Crest A transverse wave moves up and down or side to side. Compression Trough Normal A longitudinal wave moves back and forth. 500 Points Rarefaction

This wave on the EM spectrum passes the most energy because it has the highest frequency. 100 Points

Gamma Rays 100 Points

Order the states of matter from the poorest transmitter of sound, to the best transmitter of sound. 200 Points

Gas Liquid Solid (Poorest) (Best) 200 Points

the lightning before you Why is it that you see the lightning before you hear the thunder? 300 Points

Sound waves travel much slower than light waves! 300 Points

Draw the molecular arrangement for the three states of matter, describing the shape and volume of each. 400 Points

Solids – definite shape and volume Liquids – indefinite shape, definite volume Gases – indefinite shape 400 Points

properties that affect *BONUS (100 extra points): Name and describe the three main properties that affect the speed of sound. *BONUS (100 extra points): the fourth factor. 500 Points

500 Points (1) Temperature - hot materials (2) Density - more dense materials (3) Medium - solids *Elasticity - (the ability of a material to bounce back after being disturbed) more elastic materials 500 Points

If a wave passes a certain point 100 times in one second, this is the measurement of its frequency. 100 Points

100 Hertz 100 Points

This wave property affects how high or low the pitch of a sound is that you hear. 200 Points

Frequency 200 Points

Identify the three different ways to find the wavelength of a transverse wave. 300 Points

Crest-to-Crest Trough-to-Trough Normal-to-Normal 300 Points

As a sound wave’s wavelength gets shorter, its frequency, or pitch, does this. 400 Points

The frequency gets higher, so the pitch gets higher High Frequency 400 Points

The intensity, or amount of energy in a wave, can be calculated by measuring the distance between these two points. 500 Points

From normal-to-crest, or normal-to-trough. 500 Points

This type of reflection occurs when a light wave hits a smooth, flat surface such as a plane mirror, and bounces back. 100 Points

Regular Reflection 100 Points

These electromagnetic waves are responsible for transmitting your cell phone calls. 200 Points

Radio Waves 200 Points

The sky looks blue because _________ light is reflected to our eyes, while _________ light is absorbed into the atmosphere. 300 Points

Blue light is reflected, while all other colors are absorbed! 300 Points

This wave property helps the Electromagnetic spectrum. us tell the difference between the waves of the Electromagnetic spectrum. 400 Points

The wavelength and frequency 400 Points

500 Points Describe what happens to light as it hits a transparent material, (2) a translucent material, and (3) an opaque material. 500 Points

500 Points (1) Transparent – most light is transmitted, some is reflected or absorbed (2) Translucent – some light is transmitted, the rest is reflected or absorbed (3) Opaque – no light is transmitted, all light is reflected or absorbed 500 Points

Bats and dolphins use this to locate food and to navigate in the dark. 100 Points

Echolocation 100 Points

This scale is used to measure the intensity of a sound wave. 200 Points

The Decibel Scale 200 Points

This is the leading cause of hearing loss in youth today. 300 Points

Exposure to loud sounds! 300 Points

instrument that is made of 6 feet of coiled tubes, and must A student invents an instrument that is made of 6 feet of coiled tubes, and must be struck to produce sound. Classify the instrument and explain whether the pitch will be high or low. 400 Points

Percussion Low pitch – there is more material to vibrate 400 Points

Describe why a fire truck’s pitch as it moves towards siren changes pitch as it moves towards and then away from you. 500 Points

The waves become compressed as the truck moves forward which increases the frequency (pitch). As the truck moves away, the waves spread apart which decreases the frequency (pitch). 500 Points

A sound wave is an example of this type of wave. 100 Points

Longitudinal 100 Points

This wave has a frequency lower than what the human ear can hear. 200 Points

Infrasound 200 Points

Sound waves with frequencies above 20,000 Hz are called this. 300 Points

Ultrasound waves 300 Points

This is the main difference between mechanical waves and electromagnetic waves. 400 Points

a medium to travel through, while electromagnetic Mechanical waves need a medium to travel through, while electromagnetic waves do not! 400 Points

The molecules in this wave move parallel to the direction in which the energy travels. 500 Points

Longitudinal Waves 500 Points
