HMH Unit 8 (Waves) Exam Questions and Answers Solved Correctly
Transverse Waves - Answers Waves in which the particles vibrate with an up and down motion.
Wave Speed - Answers The speed at which a wave travels. Depends on the interaction of the atomic
particles of the medium.
Wave - Answers A disturbance that transmits energy through matter or space.
Hertz - Answers Frequency is expressed in this unit. One cycle per second.
Medium - Answers A substance through which a wave can travel.
Wave Period - Answers The time required for one cycle.
Trough - Answers The point where the wave is the lowest.
Amplitude - Answers A measure of how far the particles in the medium move away form rest position.
Mechanical Wave - Answers A wave that requires a medium to travel.
Speed of Light - Answers 300,000,000 m/s (3 x 10 to the 8th)
Electromagnetic Wave (EM Spectrum) - Answers A disturbance in electric and magnetic fields.
Transverse Waves. Ex: visible light, radio waves, microwaves, UV light, x-rays
Wavelength - Answers The distance from any point on a wave to an identical point on the next wave
(upside down y = lambda)
Longitudinal Wave - Answers The particles of the medium vibrate back and forth along the path that the
wave travels (also known as compression). Particles, same direction as wave travel.
Crest - Answers The point where the wave is the highest.
Sound Wave - Answers Longitudinal wave caused by vibrations and travels through a medium.
Radiation - Answers The transfer of energy as electromagnetic waves.
Reflection - Answers The bouncing back of a wave after it strikes a barrier.
Pitch - Answers How high or low you think a sound is. Determined by the frequency of the sound wave.
Loudness - Answers How loud or soft a sound is perceived to be. Increase AMPLITUDE of the wave and
this increases.
Visible Light - Answers Range of wavelengths in the EM spectrum that humans can see (longest to
shortest wavelength ROY-G-BIV or shortest to longest wavelength VIB-GYOR)
