Chapter 11, Waves

Sound waves require a medium

Light waves are electromagnetic waves.

Water waves transport energy but not water

The medium seismic waves travel through rocks and other materials inside the Earth

Sound waves are an example of longitudinal waves.

light waves are an example of transverse waves.

The following water wave is an example of a transverse waves.

The matter through which a wave travels is called the medium

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 a transverse wave.

A wav that causes the particles of the medium to vibrate parallel to the direction the wave travels is a longitudinal 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. The period of the wave is 5 seconds.

----------------------------------

The wavelength of the wave in the above diagram is 1.5 m

The amplitude of the above wave is 0.5

The wavelength is 3m

The frequency of a sound wave determines the pitch of the sound.

How loud a sound is depends on the amplitude of the waves.

The difference between visible light and x rays is that the frequency of x rays is greater.

A sine curve is a good mathematical model for representing transverse waves?

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 20m.

30. The greater the frequency of the wave in a particular medium, the greater the speed of the wave is true

31. The energy of a mechanical wave depends on the amplitude of the wave is true

32. As the period of the wave increases, the frequency increases is false.

33. The color of visible light depends on the wavelength of the light is true.

34. You call the highest point of a transverse wave the crest.

36. You call the greatest distance those particles in a medium move from their normal position when in a wave the amplitude

37. You call the time required for one full wavelength to pass a certain point a period.

38. You call the number of vibrations that occur in a 1-second time interval the frequency.
