 Which of the following relate to sound waves? Sound waves require a medium Which of the following relate to light waves? Light waves are electromagnetic waves. Which of the following relate to water waves? Water waves transport energy but not water The medium seismic waves travel through is? The medium seismic waves travel through rocks and other materials inside the Earth Sound waves are an example of transverse waves or longitudinal waves. Sound waves are an example of longitudinal waves. Light Waves are an example of transverse waves or longitudinal waves. light waves are an example of transverse waves. The following water wave is an example of? The following water wave is an example of a transverse waves. true or false – A wave transports energy but not matter true true or false – Visible light waves require a medium in which to travel false true or false – Radio waves are an example of electromagnetic waves. true true or false – Sound waves are an example of longitudinal waves, true true or false – light waves are an example of transverse waves. true medium/ The matter through which a wave travels is called the medium A wave that requires a medium is called what? A wave that requires a medium is called a mechanical wave. A wave that causes the particles of the medium to vibrate perpendicular to the direction the wave travels is what kind of wave? A wave that causes the particles of the medium to vibrate perpendicular to the direction the wave travels is a transverse wave. A wave that causes the particles of the medium to vibrate parallel to the direction the wave travel is called what? A wav that causes the particles of the medium to vibrate parallel to the direction the wave travels is a longitudinal wave. A wave has a period of a 0.25 seconds. What is the frequency of this wave? A wave that has a period of 0.25 seconds has a frequency of 4 Hz A man standing on the shore of a beach, up to his knees in water. Every 5 seconds a wave breaks on him. What is the period of the wave? A man standing on the shore of a beach, up to his knees in water. Every 5 seconds a wave breaks on him. The period of the wave is 5 seconds. ——————————– ———————————- The wavelength of the wave in the above diagram is? The wavelength of the wave in the above diagram is 1.5 m The amplitude of the above wave is what? The amplitude of the above wave is 0.5 A train of waves is moving at a speed of 30 m/s. The frequency of the waves is 10 Hz. What is the wavelength? The wavelength is 3m What does the frequency of a sound wave determine? The frequency of a sound wave determines the pitch of the sound. How loud a sound is depends on what? How loud a sound is depends on the amplitude of the waves. What is the difference between visible light and x-rays? The difference between visible light and x rays is that the frequency of x rays is greater. what kind of curve is a good mathematical model for representing transverse waves? A sine curve is a good mathematical model for representing transverse waves? The color of light is determined by what? The color of light is determined by the frequency of the light rays. . A wave with a frequency of 0.5 Hz and a speed of 10m/s has a wavelength of what? . A wave with a frequency of 0.5 Hz and a speed of 10m/s has a wavelength of 20m. 30.T/F, The greater the frequency of the wave in a particular medium, the greater the speed of the wave? 30. The greater the frequency of the wave in a particular medium, the greater the speed of the wave is true 31. T/F, The energy of a mechanical wave depends on the amplitude of the wave. 31. The energy of a mechanical wave depends on the amplitude of the wave is true 32. T/F, As the period of the wave increases, the frequency increases? 32. As the period of the wave increases, the frequency increases is false. 33. T/F, The color of visible light depends on the wavelength of the light? 33. The color of visible light depends on the wavelength of the light is true. 34. What do you call the highest point of a transverse wave? 34. You call the highest point of a transverse wave the crest. 35. What do you call the lowest point on a transverse wave? … 36. What do you call the greatest distance that particles in a medium move from their normal position when in a wave? 36. You call the greatest distance those particles in a medium move from their normal position when in a wave the amplitude 37. What do you call the time required for one full wavelength to pass a certain point? 37. You call the time required for one full wavelength to pass a certain point a period. 38. What do you call the number of vibrations that occur in a 1-second time interval? 38. You call the number of vibrations that occur in a 1-second time interval the frequency. the particle model of light explains how light can .. travel through empty space without a medium the amount of energy in a photon of light is proportional to the frequency of the corresponding light wave which type of electromagnetic waves has the highest frequency gamma rays which type of electromagnetic radiation is used to kill cancer cells? gamma rays the two most common models of light describe it a wave or as a stream of particles in the particle model of light, individual "packets ‘ of light are called photons In a vacuum all light travels as the same speed, which is ___ 3.0 x 10 to the 8 power m/s ___ is used for cooking as well as for communications microwaves
