Physical Science waves

A laser beam is aimed at four different objects. Through which of these objects will the laser beam pass and be refracted?

a glass prism

Which generates waves that are capable of traveling through a vacuum?

a light bulb

Graph:Which best describes what is happening to the light when it passes from the air and travels through the glass?

The light wave is refracted.

When John broke his arm, the doctor took an x-ray of John's arm. John had never seen an x-ray before. He asked the doctor how the x-ray was able to show his bones but not his skin and other tissue. Which explanation would the doctor best provide to John?

X-rays have higher frequency than visible light and therefore can pass through skin and tissue but not through the bone.

Which best demonstrates that waves transfer energy?

a bell ringing in a tower

Which has the longest wavelength?

red light

Which characteristic of sound makes it possible for bats to fly in the dark without hitting any objects?

reflection

The spectrum of visible light can be seen in a rainbow because white light is

refracted and dispersed.

graph:When a pencil is placed in a cup of water, the pencil looks bent.

refraction

graph: Which diagram shows the angle of reflection for the light beam?

same but opposite with 30

Which of the following would produce a longitudinal wave?

sending a compression wave through a spring toy

Which model best illustrates the wave property that enables scientists to explore Earth's interior using seismic waves?

shining a light through a prism

Which of these uses sound waves to locate underwater objects?

sonar

Which type of wave displaces its medium in the direction of its propagation?

sound

Which of the following is not an example of a transverse wave?

sound from a tuning fork

Which of the following describes diffraction?

the bending of waves as they pass an edge or an opening

Electromagnetic waves are sometimes demonstrated by rippling waves in water. However, electromagnetic waves are different from water waves. Which is a characteristic that makes electromagnetic waves and water waves different?

All electromagnetic waves can travel in a vacuum.

Which statement best describes what happened after the drop hit the still water?

Energy flowed through the water in waves.

Gamma rays are sometimes used to detect flaws in metal structures such as bridges. Why are gamma rays more useful for this application than x-rays?

Gamma rays have a shorter wavelengths so they able to penetrate metal objects.

During a baseball game, fans in the stands create a "wave" by standing up from their chairs when the wave arrives at their location. Which sentence classifies this type of wave and its particle motion?

It is a transverse wave in which the particles of the wave move in a direction perpendicular to the wave motion.

What kind of energy transfer occurs when an earthquake produces a large ocean wave called a tsunami?

Mechanical waves transfer energy from rock to water.

Which of these types of electromagnetic radiation has the lowest frequency?

Radio Wave

Emily's younger sister Amy has just learned that radio waves, like X-rays, are a form of electromagnetic energy. Amy asks Emily why radio waves aren't dangerous like X-rays. Which answer is most accurate?

Radio waves have a lower energy than X-rays.

Unlike radio waves, microwaves can be used for cooking. Which property is responsible for the difference in behavior between microwaves and radio waves?

Radio waves have longer wavelengths than microwaves.

graph: A single beam of light is shone into a glass containing milky water.

The light is moving from air into another medium.

Jeremiah was investigating different aspects of sound waves. He listened to two sounds. Sound 1 had a lower pitch than Sound 2. Based on this information, how was Sound Wave 1 different from Sound Wave 2?

Sound Wave 1 had a lower frequency than Sound Wave 2.

Which statement best describes the nature of sound?

Sound travels as longitudinal waves.

A black box and a white box are in a poorly lit room. Why is the white box easier for the eye to detect?

The black box absorbs light, and the white box reflects light.

What happens to a ray of white light when it passes through a prism?

The ray of light is bent in several pathways showing a rainbow.

Graph: Which is an observable pattern based on the data?

There is an inverse relationship between the wavelength and the frequency of light.

Graph: Which arrow shows the direction in which the P-wave propagates?

arrow c

Sound waves and ocean waves are similar in that both

carry from one place to another

The waves that are produced by a person's voice are similar to the waves produced by an earthquake because both are

caused by physical vibrations.

The range of all forms of radiant energy is called the

electromagnetic spectrum.

A student is playing with a small toy boat on a pond. The student throws a rock in the pond. This creates waves that move the boat toward the shore. The boat moves toward the shore because the waves transfer

energy

When a light bulb is used to light a room, which of the following is transferred by the light waves from the bulb to the surfaces of the room?

energy

As wave frequency is increased, wave energy

increases

Which of the following electromagnetic waves has a longer wavelength than visible light?

infrared

One technique for detecting breast cancer uses electromagnetic waves to detect temperature differences between cancer tissue and the surrounding normal tissues. What part of the electromagnetic spectrum is used in this technique?

infrared radiation

What takes place as a light wave enters a denser medium?

it is refracted

Graph:Which statement classifies the sound wave?

longitudinal wave in which the particles of the wave move in a direction parallel to the wave motion

During which activity will light most likely be refracted?

looking at pebbles through the water in a stream

Researchers are studying Europa, one of the moons of Jupiter. They are using a technique similar to sonar used by bats. Sound waves directed at the surface would travel through cracks in the ice, bounce off the surface of a liquid ocean, and echo back to the sensors. As they travel through the ocean of Europa, the sound waves would be an example of which type of energy?

mechanical

Graph: As Wave 1 moves to the right, what will the boat do?
