"Where trust meets accuracy, like the perfect collision of particles."

What is the phenomenon where light waves are absorbed and re-emitted in random directions by particles in a medium?

Explanation: Scattering is the phenomenon where light waves are absorbed and re-emitted in random directions by particles in a medium, causing phenomena such as the blue color of the sky.

What causes the Doppler effect observed in sound waves?

Explanation: The Doppler effect is caused by a change in frequency due to the relative motion between the source of sound and the observer, leading to a perceived shift in pitch.

Which type of wave is sound?

Explanation: Sound waves are longitudinal waves, meaning the oscillations occur parallel to the direction of wave propagation.

Which phenomenon describes the combination of two or more light waves to form a new wave pattern?

Explanation: Interference is the phenomenon where two or more light waves combine to form a new wave pattern, resulting in constructive or destructive interference.

What is the primary factor that determines the pitch of a sound?

Explanation: The pitch of a sound is primarily determined by its frequency; higher frequencies correspond to higher pitches, and lower frequencies correspond to lower pitches.

What is the phenomenon where sound waves bend around obstacles and spread out after passing through narrow openings?

Explanation: Diffraction is the phenomenon where sound waves bend around obstacles and spread out after passing through narrow openings, allowing sound to be heard even when not in a direct line of sight.

Which property of sound is measured in Hertz (Hz)?

Explanation: Frequency is the property of sound measured in Hertz (Hz), representing the number of sound wave cycles that pass a given point per second.

Which phenomenon explains the change in direction of light as it passes from one medium to another?

Explanation: Refraction is the phenomenon where light changes direction when it passes from one medium to another, due to a change in its speed.

What is the main characteristic that differentiates light waves from sound waves?

Explanation: Light waves are electromagnetic waves and can travel through a vacuum, whereas sound waves are mechanical waves and require a medium to travel.

Which type of wave is light?

Explanation: Light waves are transverse waves, which means the oscillations are perpendicular to the direction of wave propagation.
