Reminders

• Temporary zeroes (*0s) will go in on Friday morning for ALL unfinished lessons

• I sent out a webmail yesterday that contains recording that go over your portfolios question-by-question

• There is also a recording that goes over your Unit 4 test, question-by-question

• Remember to ask for resets, if needed!

• 12 school days left, including today!!!

What is a wave?

A wave is a disturbance that transfers energy from one location to another

Multiple Choice

Sound does not travel in space because

• Space is too far away.
• There is no matter in space.
• Space is the final frontier
• Space has planets.

Multiple Choice

What type of wave is this?

• Electromagnetic

• Mechanical

• Both Electromagnetic and Mechanical

Multiple Choice

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

• amplitude
• crest
• trough
• wavelength

Electromagnetic Spectrum

• Electromagnetic radiation is energy that travels in waves across space as well as through matter

• Characterized by certain wavelengths & wave frequencies

• Wavelength = distance between 2 corresponding points on adjacent waves

• Wave frequency = # of waves that pass a fixed point in a given amount of time

• Shorter wavelength = higher frequency

Multiple Choice

Which has the SHORTEST wavelength and, therefore, the highest frequency/most energy

• Radio waves
• Ultraviolet Rays
• Gamma Rays
• X-rays

Multiple Choice

Which electromagnetic wave can you see?

• Gamma ray

• Microwave ray

• Visible light

• X-ray

Multiple Choice

The energy of waves _______ as the wavelength gets shorter.

• increases
• decreases
• stays the same

Multiple Choice

What is the number of waves that pass a point in one second?

• Amplitude
• Frequency
• Period
• Wavelength

Next week...

We will talk more about visible light.

Wave Speed

• The speed of a wave is equal to the frequency * wavelength

Multiple Choice

 A wave has frequency of 50 Hz and a wavelength of 10 m. What is the speed of the wave?

• 500 m/s
• 50 m/s
• 5 m/s
• 0.5 m/s

Multiple Choice

One end of the rope is vibrated to produce a wave with a wavelength of .25 m.  The Frequency of the wave is 3.0 Hz.  What is the speed of the wave?

• 3.00 m/s
• 2.50 m/s
• .75 m/s
• 1.25 m/s

Multiple Choice

What is a medium?

• something between a small and a large?
• the substance through which a wave can travel
• a pattern of vibration that simulates when a wave is standing still
• the distance from any point on a wave to an identical point on the next wave
