pattern of compressions and rarefactions.

pattern of up and down vibrations.

Two waves have the following waveforms. Which conclusion can best be supported by the illustrations?

Wave B is a visible light wave.

Which of the following describes the production of a longitudinal wave and the motion of particles that transport this waveform?

A single pulse tone is sent from an underwater speaker through a pool of water and the water molecules are compressed in the direction of the wave.

A vertical pulse is sent down a rope fixed at one end and sections of the rope move up and down, while the wave travels down the length of the rope.

A coin is tossed into a calm pool of water and water particles are displaced up and down as the circular wave moves toward the edges of the pool.

A horizontal pulse is sent down a spring fixed at one end and sections of the spring move side to side, while the wave travels in down the length of the spring.

A 50-gram mass is hung from a spring clamped to a ring stand. A student pulls the mass downward from its rest position, and releases the mass-spring system, allowing it to bob up and down. The vertical position of the mass-spring system as a function of time is shown below. Which of the statements identifies the amplitude, period, and frequency of the system?

Amplitude = 10 cm; Period = 2s; Frequency = 0.5 Hz

Amplitude = 20 cm; Period = 2s; Frequency = 0.5 Hz

Amplitude = 20 cm; Period = 4s; Frequency = 0.25 Hz

Amplitude = 10 cm; Period = 4s; Frequency = 0.25 Hz

Which of the following characterizes the wave nature of sound and light?

sound is a longitudinal (compression) wave and light is an electromagnetic wave

sound is an electromagnetic wave and light is a longitudinal (compression) wave

sound and light are both longitudinal (compression) waves

sound and light are both electromagnetic waves

Marissa, Connor, and Felipe stand outside for ten minutes. Then, the temperatures of their shirts are taken as shown in the picture below. What do the temperatures of the shirts show about light?

Light can be absorbed, and darker colors absorb more light.

Light can be reflected, and darker colors reflect more light.

Light can refract to give off heat.

Light disappears into white shirts

Sunburns are caused by ultraviolet (UV) light, not visible light, even though, as the graph below shows, the visible part of sunlight is more intense than the ultraviolet part. Ultraviolet light has a shorter wavelength than visible light. Which conclusion is BEST supported by this information?

Shorter wavelength electromagnetic radiation has more energy.

Shorter wavelength electromagnetic radiation has higher speed.

Shorter wavelength electromagnetic radiation has greater charge.

Shorter wavelength electromagnetic radiation has greater mass

A student reads that radio waves are considered safe, while X-rays are dangerous. The student examines an electromagnetic spectrum shown below. Based on this information, which statement can the student BEST make to explain the difference between radio waves and X-rays?

The shorter wavelength of X-rays indicates that they have more energy.

The shorter wavelength of X-rays indicates that they are less common.

The shorter wavelength of X-rays indicates that they have a higher temperature and can more easily cause burns.

The shorter wavelength of X-rays indicates that their particles are heavier and can travel farther through matter.

What is true about most of the wavelengths found in the electromagnetic spectrum?

They are invisible to the human eye.

They travel only through prisms.

They are found in the visible light range.

A student is told to propose a design for a device capable of producing an image like the one shown below of the interior of the human body. Which statement BEST explains why the student should propose the use of X-rays by the device?

The high energy of X-rays allows them to pass through the human body.

The rarity of X-rays in nature means they can be used in machines without other X-rays blurring images.

The high speed of X-rays allows them to be used safely on human patients.

The brightness of X-rays means they last a long time once they are produced by a machine.

What happens to the speed and frequency of a ray of light when it passes from air into water?

The speed decreases, and the frequency remains the same.

The speed increases, and the frequency increases.

The speed decreases, and the frequency increases.

The speed increases, and the frequency remains the same.
