Introduction to Waves

Explore the fascinating world of waves! Learn key properties and types.

Waves transfer _ but not _. matter, energy energy, matter energy, sound sound, energy Frequency is… a point on a wave to that same point on the adjacent wave the measure of how much energy a wave carries the number of cycles per unit of time the time it takes to complete one cycle The unit for frequency is… meters kilograms seconds hertz Period is… a point on a wave to that same point on the adjacent wave the measure of how much energy a wave carries the number of cycles per unit of time the time it takes to complete one cycle The unit for period is… meters kilograms seconds hertz Wavelength is… a point on a wave to that same point on the adjacent wave the measure of how much energy a wave carries the number of cycles per unit of time the time it takes to complete one cycle The unit for wavelength is… meters kilograms seconds hertz Amplitude is… a point on a wave to that same point on the adjacent wave the measure of how much energy a wave carries the number of cycles per unit of time the time it takes to complete one cycle A wave in which the vibrating element moves in a direction perpendicular to the direction of advance of the wave. transverse longitudinal surface A wave in which the vibrating element moves in a direction parallel to the direction of advance of the wave. transverse longitudinal surface Label the Longitudinal Wave compression rarefaction Label the Transverse Wave trough amplitude crest wavelength Visible light is an example of a _ wave. transverse longitudinal surface Sound is an example of a _ wave. transverse longitudinal surface The equation for the speed of a wave is v = T*f λ=v*f v = λ*f f = λ*v Remember:1. Period is the time it takes to complete one cycle and is measured in seconds.2. The formula for Period (T) is T= 1 where f is the frequency.2. Frequency is the number of cycles per unit of time and is measured in hertz.4. The formula for Frequency (f) is f= 1 where T is the period.A string vibrates with a frequency for 10 Hz. What is the period? 10 1.0 .10 A speaker vibrates at a frequency of 400 Hz. What is the period? .0025 .04 .4 A pendulum has a period of 0.5 sec. What is the frequency? 5 2 .25 A swing has a period of 20 seconds. What is the frequency? 10 .5 .05
