Waves

Waves and energy

By Angélica Manzanarez

The waves transmit energy, they do not transmit matter​

​

A lot of waves need a medium such as water or air to exist​

A wave is a periodic back and forth

Multiple Choice

A seismograph used to

• measures the weather
• takes a picture of the clouds
• used to detect and measure earthquake wave
• detects waves of the ocean

Multiple Choice

A wave carries...?

• energy only
• matter only
• the matter carries the energy
• neither

Multiple Choice

The highest point on a wave is:

• the crest
• the trough
• the top
• the coast 

Multiple Choice

The lowest point on a wave is the:

• Amplitude
• Crest
• Trough
• Wavelength

In transverse waves, the particles are transmitted at right angles to the direction of the wave.

​

In longitudinal waves, particles of the medium move in the same direction as the ​wave.

​

Types of waves​

Multiple Choice

What type of wave is this?

• Longitudinal
• Transverse

Wave attributes

Multiple Choice

What property of this wave is represented by the letter "A"

• amplitude
• crest
• trough
• wavelength

Multiple Choice

What property of the wave is represented by the letter "B"?

• amplitude
• crest
• trough
• wavelength

Multiple Choice

The number of wavelengths that pass a point each per second is:

• frequency
• period
• longitudinal 
• transverse wave 

Multiple Choice

Which is the correct equation for calculating the speed of a wave?

• T = 1/f
• Speed= Wavelength x Period
• Speed = Wavelength/Frequency
• Speed= Wavelength x Frequency

Multiple Choice

Which wave in the diagram has the greatest frequency?

• 1
• 2
• 3
• 4

Multiple Choice

Which wave in the diagram has the greatest wavelength?

• 1
• 2
• 3
• 4

Multiple Choice

What is the amplitude of a wave?

• how often a wave passes a certain point

• the distance from the middle of the wave to a crest or a trough

• the highest point of a wave

• chick-fil-a

Multiple Choice

What is the unit for frequency?

• Meters

• Hertz

• Decibels

• Meters/Second

Multiple Choice

When the frequency of a wave decreases, the ____________________________________ of the wave increases.

• wave speed

• amplitude

• wavelength

• Doc McStuffins

When a wave strikes an obstacle or a boundary, the wave may bounce off the surface of the obstacle in another direction

​

The waves that strike the obstacle are indicent waves, the waves that "bounce" off the object are called reflected waves.

Reflection of a wave

​

The bending of the path of a wave as a result of wave speed is refraction

​

​Refraction of a wave

​

The diffraction causes the wave to spread out evenly when the opening is roughly equal to one wavelength

​
