Sound and Light Waves

Front

What is amplitude in sound waves?

Back

Amplitude refers to the height of the wave, which determines the loudness of the sound. A higher amplitude means a louder sound.

Front

What does frequency measure in sound waves?

Back

Frequency measures the number of vibrations or cycles per second in a sound wave, determining the pitch of the sound.

Front

What is the relationship between pitch and frequency?

Back

Higher frequency results in a higher pitch, while lower frequency results in a lower pitch.

Front

Define reflection in the context of waves.

Back

Reflection is the bouncing back of a wave when it hits a surface, such as light bouncing off a mirror.

Front

What is a medium in wave propagation?

Back

A medium is the substance or material through which a wave travels, such as air, water, or solid materials.

Front

Explain refraction in waves.

Back

Refraction is the bending of waves as they pass from one medium to another, changing speed and direction.

Front

What is diffraction?

Back

Diffraction is the spreading out of waves when they pass through a narrow opening or around obstacles.

Front

How does sound travel through different mediums?

Back

Sound travels fastest through solids, slower through liquids, and slowest through gases due to the density and elasticity of the medium.

Front

What is the speed of sound in air at room temperature?

Back

The speed of sound in air at room temperature (20°C) is approximately 343 meters per second.

Front

What is the difference between a sound wave and a light wave?

Back

Sound waves are mechanical waves that require a medium to travel, while light waves are electromagnetic waves that can travel through a vacuum.
