Waves Unit- Part Two (re:2024)

Front

What is intensity in the context of waves?

Back

Intensity is defined as the amount of energy in each wave.

Front

How does the medium affect the speed of mechanical waves?

Back

Mechanical waves can travel fastest through a solid.

Front

What is pitch in relation to sound waves?

Back

Pitch is how high or low a sound is perceived, depending on the frequency of the wave.

Front

What are the three stages of sound comprehension?

Back

1. Gathering and amplification of longitudinal waves by the ear mechanism. 2. Conversion of waves into nerve impulses. 3. Decoding of nerve impulses in the brain to recognize sound.

Front

What property of a sound wave is related to its volume?

Back

Volume is related to the amplitude of the sound wave.

Front

What is the relationship between frequency and pitch?

Back

The frequency of a wave determines the pitch of the sound; higher frequencies correspond to higher pitches.

Front

What is the definition of amplitude in wave physics?

Back

Amplitude is the maximum extent of a wave's oscillation, which relates to the energy and volume of the wave.

Front

How do sound waves travel through different media?

Back

Sound waves travel through solids, liquids, and gases, with speed varying based on the medium's density and elasticity.

Front

What is the difference between longitudinal and transverse waves?

Back

Longitudinal waves oscillate parallel to the direction of wave travel, while transverse waves oscillate perpendicular to the direction of wave travel.

Front

What role does the ear play in sound comprehension?

Back

The ear gathers sound waves, amplifies them, converts them into nerve impulses, and sends them to the brain for decoding.
