1) Waves are disturbances that carry? a) amplitude b) energy c) refraction 2) Constructive waves are when a) 2 or more waves combine and make a larger single wave b) bending of the wave c) 2 or more waves that combine and produce a smaller wave 3) Sound waves are a) compressional waves b) light waves c) frequency 4) Two types of waves a) mechanical and non mechanical b) transverse waves c) compressional waves 5) Which waves need a medium to travel through? a) mechanical b) nonmechanical c) energy 6) Which phase of matter does sound travel the fastest and why? a) solids because they are closer together b) liquids because the particles are more spread out c) gases because the particles are most spread out 7) Sound is made by a) crest b) amplitude c) nonmechanical waves d) a vibrating object 8) How is amplitude and energy related in a transverse wave? a) the lower the amplitude the more the energy b) the higher the amplitude the more energy the wave is carrying c) Examples are light, gamma waves and x-rays 9) Where is the wave length located on a transverse wave? a) from trough to trough b) from crest to crest c) from amplitude to amplitude 10) Transverse waves move a) back and forth b) up and down c) by doppler effect 11) The highest point on a transverse wave a) amplitude b) crest c) trough 12) Destructive interference a) cancels out to become a smaller wave b) comes together to build up to make a larger wave c) bounces off 13) What is reflection a) The bouncing off b) bends through something c) bends around an object 14) A compressional wave is when a)  the particles move in the same direction as the wave b) spread out c) movement of up and down 15) Frequency of a wave is a) material that a wave travels through b) when particles move in the same direction as the wave c) measures the number of waves produced each second 16) When a wave bends because of the change of speed as it passes from one medium to another a) wave length b) wave c) refraction d) compressional 17) What unit is used to measure frequency? a) Hz b) m/s c) m 18) The frequency of a sound wave determines the a) sound b) pitch c) pressure d) frequency 19) Sound is measured in a) decibels b) m/s c) meters d) energy 20) Loudness depends on and this means pressure a) doppler effect b) diffraction c) amplitude 21) When the sound hits an object and an echo comes back a) sound waves b) echolocation c) doppler effect 22) Sound waves bunch up in front of a source causing a high pitch and spread out behind the source causing a low pitch a) sound waves b) echolocation c) doppler effect 23) Radio waves a) have the lowest frequency and the longest wavelengths b) have the highest frequency and the shortest wavelengths c) an example is a tanning bed 24) Have the highest frequency and the shortest wave length a) ultraviolet waves b) infrared rays c) gamma rays d) visible ligth 25) Light ways are? a) mechanical and they need a medium b) nonmechanical and do not need a medium 26) The color of light is determined by a) reflection b) absorbs c) medium 27) Red objects reflect the color and absorb all other colors of light a) black b) green c) red 28) Black objects a) absorbs colors of all light and absorbs all colors of light b) reflects all colors of light and reflects no colors of light c) turn white
