Waves

Master waves! Learn transverse & longitudinal types, wavelength, amplitude, and more with our interactive worksheet.

#1.) Which type of wave is this? Transverse Longitudinal Both Neither #2.) Which type of wave is this? Transverse Longitudinal Both Neither #3.) Sort the characteristics under each type of wave. Transverse Waves Also called electromagnetic waves Movement is up and down An example is light Travel perpendicular to the medium Can travel through a medium or a vaccuum Longitudinal Waves Also called mechanical or compression waves Movement is back and forth An example is sound Travel parallel to the medium Can only travel through a medium How is the wavelength of a longitudinal wave measured? Crest to crest or trough to trough From beginning to end From middle of one compression to the middle of the next. Both A and B What is the wave frequency in this picture? 3 4 4.5 8 Which object will absorb the most amount of visible light energy if placed in the direct sunlight? A piece of glass A blue bowling ball A shiny mirror A white baseball A snowball A black soccer ball Label the wave below, do not capitalize. wavelength trough amplitude crest Matching Concave Convex Reflection Refraction Sound travels as vibrations in longitudinal waves. Sound waves require a medium to travel through, and they cannot travel through empty space. Sound travels faster through more dense matter such as solids and liquids, and slower in gases. Matching Animals using sound waves to help navigate or locate objects Echolocation Sound technology used to determine the distance between objects and used on submarines SONAR Sound technology used in medicine to help visualize soft tissue in humans Ultrasound When light passes through a new medium Transmission When light enters a new medium, but does not pass through Absorption Bending of light wave when it enters a new medium Refraction Bouncing back of a wave when it hits a new medium Reflection All of these are true, EXCEPT ultraviolet light has more energy than visible light Gamma rays have highest frequency Radio waves are used for communication Humans can feel the warmth from ultraviolet Radio waves have the largest wavelength Humans can see visible light Wave frequency is the number of waves produced over a given period of time. There is a(n) inverse relationship between frequency and wavelength and a direct relationship between frequency and energy. As the frequency of a wave increases, the wavelength decreases. As the frequency of a wave increases, the energy increases. Also, more energy can increase the amplitude of a wave which is seen as larger crests and troughs. Matching The bouncing of a sound off of a surface Echo Increasing the amplitude of a wave increases the Loudness Increasing the frequency of a wave increases the Pitch Vibrations from one object cause a nearby object to vibrate at the same frequency Resonance When two or more waves combine to form a new wave pattern Interference Which is not true? Wave A has a larger wavelength Wave B has higher amplitude Wave A has a frequency of 2 Wave B has higher energy Wave A is a transverse wave Wave B has a higher frequency If the angle of incidence is 50 degrees, what would the reflected angle be? 40 50 90 130 Label this wave, no capitalization wavelength rarefaction compression Why do we see an airplane overhead before we hear the roar of its jets? Sound travels faster than light Our eyes are more sensitive than our ears Light travels faster than sound Most airplanes are moving faster than the speed of sound When light enters a new medium it can bounce off or reflect, go in and scatter (be absorbed) or pass through, which is called transmission. Sometimes, light bends when it enters a new medium, this is called refraction. This occurs because when light enters a new medium, the speed of light changes due to the different density of the medium.
