Waves Review
Recognize different types of waves and label their structures.
1. What type of wave is represented in the diagram?
2. The area labeled “X” is called the
.
3-7. Label the wave
8. What is true of both transverse and compressional waves?
Calculate wavelength, frequency, and wave velocity.
9. If a sonar signal has a frequency of 322 Hz and a wavelength of 5 m, how fast does
the sound travel through the water?
10. The lowest pitch that the average human can hear has a frequency of 20.0 Hz. If
sound with this frequency travels through air with a speed of 340 m/s, what is its
wavelength?
11. Red light and violet light travel at the same speed. If red light has a frequency of
450,000 Hz and a wavelength of 700 nm and violet light has a wavelength of 420 nm,
what is its frequency?
Interpret wave diagrams.
12. What is the frequency of the following wave?
13. Which wave has the longest wavelength?
14. Which wave has the highest frequency?
Identify factors that can change the direction of a wave.
15. A bat emits a series of short, high-pitched sounds that bounce off an object to give
the bat a sense of what is in its path. Which wave behavior is occurring?
16. In the diagram above, the fish is in a particular location, but the person looking
into the water sees the image of the fish in a different location. Which wave behavior is
causing the fish to look like it is somewhere that it isn’t?
17. Why does a black shirt look black?
Diagram different wave behavior.
Name the wave behavior shown in each diagram.
Predict how a wave will behave in different situations.
23. A wave approaches a barrier. What will happen to the wave as it goes around the
barrier?
24. A sound wave strikes a very smooth, hard surface. What will happen to the wave?
Describe features of sound.
25. The speed of sound depends on
and
.
26. The loudness of a sound made by plucking a guitar string is determined by the
.
27. The Doppler effect is an apparent change in the wavelength, but the wave emitted
by the source is actually constant. As a train approaches and blows its horn, the
apparent decrease in the wavelength will make the horn sound
.
28. A submarine sonar transmitter emits a burst of waves while submerged. The time
that it takes the waves to travel to an object and return to the submarine tells the
submarine operator the distance to the object. What type of wave is used by sonar
transmitters?
29. During a thunderstorm, you see lightning before you hear thunder because
30. Ultrasound waves are used in medicine to produce computerized images called
sonograms. A person having an ultrasound cannot hear the sound waves being used.
Why not?
Describe features of the electromagnetic spectrum.
Label the electromagnetic spectrum.
34. An electromagnetic wave is traveling at 3.00 X 108 m/s and has a wavelength of
1000 nm. What type of wave is it?
35. Which end of the electromagnetic spectrum has the most energy?
36. As the energy of light increases, which of these also increases?
37. Which type of electromagnetic wave can be used for communication?
38. Why is UV light more damaging to your skin than visible light?
