Wavelength vocabulary test

define wave

• A wave is a type of dessert
• A wave is a type of dance move
• A wave is a type of weather pattern
• A wave is a disturbance that travels through a medium, transferring energy from one point to another without causing any permanent displacement of the medium itself.

define medium

• A type of fabric
• A means of communication that reaches a large number of people
• A method of cooking
• A small size

define crest

• A type of bird.
• The highest point of a wave or a hill.
• The lowest point of a wave or a hill.
• A type of toothpaste.

where is the trough in a wave

• The trough in a wave is located at the bottom of the wave.
• The trough in a wave is located on the side of the wave.
• The trough in a wave is located in the middle of the wave.
• The trough in a wave is located at the top of the wave.

define wavelength

• The distance between successive crests of a wave
• The frequency of a wave
• The amplitude of a wave
• The speed of a wave

define frequency

• The pitch of a sound
• The amplitude of a wave
• The speed of light in a vacuum
• Number of occurrences of a repeating event per unit of time

define mechanical wave

• A mechanical wave is a wave that does not require a medium to transfer energy
• A mechanical wave is a wave that only travels through a vacuum
• A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.
• A mechanical wave is a wave that is not affected by the properties of the medium it travels through

define longitudinal wave

• A wave that only travels in a straight line
• A wave in which the displacement of the medium is perpendicular to the direction of energy transport
• A wave that does not require a medium to propagate
• A wave in which the displacement of the medium is in the same direction as, or the opposite direction to, the direction of energy transport.

define electromagnetic wave

• An electromagnetic wave is a wave that is created as a result of oscillating electric and magnetic fields.
• An electromagnetic wave is a wave that is created by chemical reactions
• An electromagnetic wave is a wave that is created by gravitational forces
• An electromagnetic wave is a wave that is created by sound vibrations

define transparent

• Blocking light from passing through
• Reflecting light instead of allowing it to pass through
• Being completely opaque
• Allowing light to pass through
