Answer: Loudness is determined by the amplitude of the sound wave.
Answer: Resonance occurs when driving frequency matches natural frequency.
Answer: Waves slow down in a denser medium while frequency stays constant.
Answer: Diffraction is the bending and spreading of waves around obstacles.
Answer: Light travels at maximum speed (3x10^8 m/s) in vacuum.
Answer: Wavelength is the distance between two consecutive identical points.
Answer: Sound waves are longitudinal waves with compressions and rarefactions.
Answer: Rainbows form from refraction, dispersion, and internal reflection in water droplets.
Answer: Refractive index n = c/v, speed in vacuum over speed in medium.
Answer: Wave speed equals frequency times wavelength.
Answer: Pitch is determined by the frequency of the sound wave.
Answer: Frequency depends on the source and does not change.
Answer: Constructive interference occurs at integer multiples of wavelength.
Answer: Superposition applies to all types of waves.
Answer: Speed of sound increases with temperature as molecules move faster.
Answer: Sound must travel 34 m round trip at 340 m/s in 0.1 s, so 17 m.
Answer: Speed of sound in air is approximately 343 m/s.
Answer: Nodes are points of zero displacement in a standing wave.
Answer: TIR occurs from denser to rarer medium when angle exceeds critical angle.
Answer: Doppler effect causes apparent frequency change due to relative motion.
