Sound and Light Waves Review

Front

What is resonance in sound waves?

Back

Resonance is the phenomenon that occurs when an object vibrates at its natural frequency due to an external force, resulting in a significant increase in amplitude of the sound.

Front

What is sound?

Back

Sound is a disturbance that travels through a medium (like air, water, or solids) as a longitudinal wave, characterized by compressions and rarefactions.

Front

What does reflection mean in the context of light waves?

Back

Reflection is the bouncing back of light waves when they hit a surface that does not absorb the light.

Front

What is frequency in terms of waves?

Back

Frequency is the number of wavelengths that pass a given point in one second, measured in Hertz (Hz).

Front

What is energy in the context of waves?

Back

Energy is the capacity to do work, and in the context of waves, it refers to the ability of waves to transfer energy through a medium.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive points in phase on a wave, such as crest to crest or trough to trough.

Front

What is pitch?

Back

Pitch is the perceived frequency of a sound; higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

Front

What is absorption in relation to sound and light?

Back

Absorption is the process by which a material takes in sound or light energy, preventing it from being reflected or transmitted.

Front

What is refraction?

Back

Refraction is the bending of light waves as they pass from one medium to another, due to a change in their speed.

Front

What is the relationship between amplitude and sound?

Back

Amplitude refers to the maximum extent of a vibration or oscillation, which determines the loudness of a sound; greater amplitude means a louder sound.
