Semester Exam- Fall Topics

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that points on a wave, such as the crest or trough, move from their rest position. It is a measure of the wave's energy.

Front

What is a longitudinal wave?

Back

A longitudinal wave is a type of wave in which the particles of the medium move parallel to the direction of the wave's travel. An example is a sound wave.

Front

Which medium does sound travel best through?

Back

Sound travels best through solids because the particles are closer together, allowing for faster transmission of sound waves.

Front

What causes Earth's seasons?

Back

Earth's seasons are caused by its revolution around the Sun and the tilt of its axis, which affects the angle and intensity of sunlight received.

Front

What is a crest in a wave?

Back

A crest is the highest point of a wave, representing the maximum displacement of the medium from its rest position.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a wave, representing the minimum displacement of the medium from its rest position.

Front

What is wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave. It determines the wave's frequency and energy.

Front

What is the difference between transverse and longitudinal waves?

Back

In transverse waves, particles move perpendicular to the direction of wave travel, while in longitudinal waves, particles move parallel to the direction of wave travel.

Front

How does temperature affect the speed of sound?

Back

The speed of sound increases with temperature because warmer particles vibrate faster, facilitating quicker transmission of sound.

Front

What is the role of gravity in Earth's seasons?

Back

Gravity itself does not cause seasons; however, it keeps Earth in orbit around the Sun, which, combined with Earth's tilt, leads to seasonal changes.
