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 of the following best describes the principle being used?
Resonance
Ultrasound
Reflection
Refraction
Students used rope to model radio waves and microwaves. Compared to the model of radio waves, the model of microwaves has a greater-
period
amplitude
frequency
wavelength
A student uses a springy metal coil to model a wave, as shown below. Which type of wave is most like the student's model?
Transverse wave
Longitudinal wave
Standing wave
Diffraction wave
Which of the following has the shortest wavelength?
A dog growling at a frequency of 85 Hz
A cello played at a frequency of 150 Hz
A male teacher speaking at a frequency of 520 Hz
A female American Idol contestant singing at a frequency of 2,100 Hz
Which of the following wave interactions happens inside a material rather than at the surface of the material?
Reflection
Refraction
Diffraction
Absorption
A veterinarian installs a programmable microchip under the skin of a new pet that, when scanned, gives off a signal that indicates the name of the owner and the vaccinations the pet has been given. What type of wave would be the safest and most effective for this microchip to use?
Microwaves
Radio Waves
Light Waves
Infrared Waves
A submarine sonar transmitter emits a burst of waves while submerged. The waves reflect off an object in the distance and return to the submarine. The time that it takes for the waves to travel to the object and return to the submarine tells the sonar operator-
the distance of the object from the submarine
the contents of the object
the weight of the object
the wavelength of the object
Two students are modeling waves using a length of rope between them, as shown below. Based on the information above, what will most likely occur when the two waves interact?
Interference
Reflection
Refraction
Diffraction
The blinds are closed in a room during the daytime and all of the lights are off. Which of the following best explains why the room may still not be completely dark and you can still see all around the room?
Light is absorbed by the blinds.
Light changes direction when entering through the window.
Light reflects off of the windows.
Light bends around the blinds.
As ocean waves approach coastlines with shallower water, the waves slow down because of the force exerted on them by the seabed. Waves coming into the shore at an angle will change direction because the part of the wave nearest the shore is in shallower water than the rest of the wave. Which of the following processes best describes the behavior of the waves?
Interference
Reflection
Refraction
Diffraction
Waves superimpose on one another when two or more waves arrive at the same point and occupy the same space. Which of the following processes best describes this behavior?
Reflection
Refraction
Diffraction
Interference
Propagating vibrations that carry energy outward in all directions from the source are used to study the interior of the Earth. These types of waves are known as
water waves
seismic waves
sound waves
light waves
What happens to the speed and frequency of a light wave when it passes from water into air?
The speed increases, and the frequency remains the same.
The speed increases, and the frequency decreases.
The speed decreases, and the frequency remains the same.
The speed decreases, and the frequency increases.
