Why can't sound travel through a vacuum?
Because sound waves are electromagnetic and need air to travel.
Because sound requires a medium to propagate pressure disturbances.
Because sound waves are too weak to exist without gravity.

Frequency
Invisible pulses of frequency shape everything from color to communication

How does frequency influence the characteristics of waves in different phenomena?
Frequency determines the pitch of sound, color of light, and signal channels in communication.
Frequency only affects sound waves and has no impact on light or radio waves.
Frequency is unrelated to wavelength and energy in wave phenomena.

What is the primary advantage of interferometry in scientific measurements?
It uses sound waves to measure distances over large scales.
It relies on direct visual observation rather than wave interactions.
It can detect extremely small differences in distance or changes by analyzing wave interference patterns.

What key factor differentiates sound waves from electromagnetic waves like light?
Sound waves travel faster than electromagnetic waves in a vacuum.
Sound waves require a medium to propagate, while electromagnetic waves do not.
Sound waves can travel through a vacuum just like light waves.

Polarized Light
Polarized light reveals hidden patterns and reduces glare by aligning wave oscillations

Why can light waves be polarized while sound waves in air cannot?
Because sound waves travel faster than light waves, preventing polarization.
Because sound waves have no oscillations and thus cannot be polarized.
Because light waves are transverse waves with oscillations perpendicular to their direction of travel, allowing orientation of oscillations, whereas sound waves in air are longitudinal with oscillations along the direction of travel.

Angle of Reflection
The angle of reflection governs everything from mirrors to sonar echoes in nature and technology
7 Feb 2026
0
What fundamental principle explains why the angle of reflection equals the angle of incidence for waves striking a surface?
The angle of reflection is always half the angle of incidence.
Waves reflect at random angles unrelated to the angle of incidence.
The law of reflection states that the angle of incidence equals the angle of reflection.

Why can't longitudinal waves, such as sound waves in air, exhibit polarization?
Because longitudinal waves have no oscillations and thus cannot be polarized.
Because their oscillations occur in the same direction as wave propagation, leaving no perpendicular component to define polarization.
Because longitudinal waves travel faster than transverse waves, preventing polarization.

Doppler Effect
The Doppler effect reveals how motion changes the pitch and frequency of waves perceived by observers
31 Jan 2026

How does the Doppler effect explain the change in pitch of a siren as an ambulance passes by an observer?
The sound waves are compressed as the ambulance approaches, increasing frequency and pitch, and stretched as it moves away, decreasing frequency and pitch.
The siren changes its pitch intentionally to alert people as it moves.
The pitch remains constant but the observer's ears perceive it differently due to sound reflection.

Resonance
Resonance amplifies vibrations when external forces match a system's natural frequency

0
Why can resonance lead to structural failure in some systems?
Because the system vibrates with a large amplitude that can cause damage or fatigue
Because resonance causes the system to stop vibrating completely
Because resonance reduces the energy absorbed by the system

What type of wave are sound waves and how do they propagate through a medium?
Sound waves are longitudinal mechanical waves that propagate through compressions and rarefactions in a medium.
Sound waves are transverse waves that propagate by oscillations perpendicular to the direction of travel.
Sound waves do not require a medium and can propagate through a vacuum.
