A wave is any disturbance that transmits ___________ through matter or space. | |
The material or substance through which a wave may travel is called the ____________. | |
Sound waves travel by ___________ of particles. | |
Waves that require a medium are called ______________ waves. | |
Waves that do not require a medium are ___________________ waves. | |
Sound travels faster in a solid than a liquid or a gas. That is because the denser or more concentrated the medium, the ____________ sound will travel. | |
A transverse wave that does not require a medium is called an ____________________ wave. | |
___________ waves are waves in which the particles of the medium vibrates in an up and down motion. | |
Particles of a transverse wave move _________________ to the direction that the wave is traveling. | |
The _________ is the highest point of a transverse wave. | |
The _________ is the lowest point of a transverse wave. | |
The ___________ of a wave is the maximum distance of the wave vibration from its rest position to the crest. | |
The _________ position of a wave is where the particles of a medium stay when there are no disturbances. | |
The larger the amplitude, the greater the ___________ of the wave. | |
_______________ is the distance between two adjacent crests or compressions in a wave. | |
______________ is the number of waves produced in a given amount of time. | |
Frequency is expressed in ____________ (Hz). | |
Higher frequency, just like higher amplitude, means more ______________. | |
Sound waves travel fastest in _____________ and slowest in air. | |
The __________ of a sound wave is directly related to the frequency. | |
A dog whistle has a _____________ frequency. | |
_____________ waves are waves in which the particles of the medium vibrate back and forth along the path that the wave travels. | |
A _____________ is a section of longitudinal wave where the particles are crowded together. | |
A _____________ is a section of the wave where particles are less crowded. | |
_________ waves are longitudinal waves. | |
List the seven types of electromagnetic waves in the electromagnetic spectrum - from lowest frequency to highest frequency. | |
_____________ occurs when a wave bounces back after striking a barrier. | |
Reflected sound waves are called an _______. | |
Light travels at different speeds in different materials. This is why light ___________, or bends as it enters a new substance. | |
The surface of a red apple __________ all the colored light rays, except for red. | |
The red light from an apple is _____________ to the eye. | |
___________ is the bending of waves around a barrier or through an opening. | |
___________ waves travel around corners better because it has larger wavelengths than light. | |
____________ is when light is taken in by an object. | |
