Light and Sound Waves Review

A light source sends light waves through a small opening in a piece of paper to a screen. The diagram shows the setup.

Choose a word or phrase in each set of parentheses to describe the most likely effect that the opening in the paper will have on the light waves

The light waves will be diffracted by the opening in the paper, causing the light waves to

( cancel out / come together / spread out ) and appear ( brighter / dimmer / equally bright

• Cancel/ Brighter

• Cancel/ Dimmer

• Spread out/ Brighter

• Spread out / Dimmer

• Come together/ Dimmer

A student uses three different-sized metal container lids to produce sounds. The student has the three metal lid sizes shown in the table. The student strikes the 45-cm lid to produce a sound. If the student wants to produce a higher-pitched sound, which method should the student most likely use?

• striking the same lid with more force

• striking the 60-cm lid with the same amount of force

• striking the 30-cm lid with the same amount of force

• striking the same lid with the same force but from farther away

• as fast as Coach Poock

What happens to the frequency of a EM wave if the wavelength gets shorter?

• frequency increases

• frequency decreases

• frequency stays the same

• what's frequency???

What is the best description of these sounds?

• All of the sounds show variation in pitch over the 40-second interval, with sound R being the loudest at the end of the recording.

• All of the sounds have the same pitch over the 40-second interval, with sound R being the loudest at the end of the recording.

• All of the sounds show variation in pitch over the 40-second interval, with sound S being the loudest at the end of the recording.

• All of the sounds have the same pitch over the 40-second interval, with sound R being the loudest at the end of the recording.

Two guitar strings that have the same length but different amounts of tension are mounted on a wooden board and plucked with a guitar pick to produce the standing waves shown in the diagram.

How does the sound compare between the two guitar strings?

• The two guitar strings produce sound at the same volume due to having the same wavelength.

• The two guitar strings produce sound at the same pitch due to having the same wavelength.

• The two guitar strings produce sound at different volumes due to having different frequencies.

• The two guitar strings produce sound at different pitches due to having different frequencies.

Use the image to answer question.

A student slides a finger around the rim of a glass, as shown, and observes a ringing sound from the glass at a certain frequency.

What aspect of sound waves does the student observe?

• resonance

• absorption

• refraction

• transmission

The diagram shows a research vessel using sonar to map the ocean floor.

Upon which basic behavior of sound waves does this technology depend?
