It is a periodic disturbance that moves away from a source and carries energy with it
Waves
The high points are called ________.
crests
It describes all the kinds of light, including those the human eye cannot see.
Electromagnetic Spectrum
It is the time taken to generate one complete wave. It is also the time taken for the crests, or any given point on the wave, to move a distance of one wavelength.
Period/Time
It is a wave in which particles of the medium move in a direction perpendicular to the direction that the wave moves
Transverse waves
The low points are called ________.
troughs
EM Spectrum is an example of __________.
electromagnetic waves
It is the distance moved by a wave in one second.
Speed
It is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
It is the maximum displacement from the rest position. It is the height of the crest or depth of a trough measured from the normal undisturbed position.
amplitude
In EM Spectrum, it has the highest frequency.
gamma ray
It is the number of crests or troughs that pass a point per second.
Frequency
What is the difference between electromagnetic and mechanical waves?
Electromagnetic waves can transmit its energy through a vacuum while mechanical wave cannot transmit energy through a vacuum.
It is the distance between two successive crests or two successive troughs
In electromagnetic spectrum, it has the longest wavelength.
radio waves
The frequency of some approaching ocean waves is 4 Hz and the length between two wave crests is 7 m. What is the speed of the ocean waves moving towards the shore?
28 m/s
Two categories in describing waves
1. direction of the movement of the waves
2. ability and inability to transmit energy through a vacuum
It is an example of a wave in which it is easily produced and observed.
water waves
The longer the wavelength, the ___________ the frequency.
lower
A wave of wavelength 4 m travels down a rope at a speed of 7 m/s. What is the frequency of the wave?
1.75 Hz
