A little of Everything :)
100
This is a disturbance that transfers energy from place to place
What is a wave?
100
This is the interaction of two waves that meet.
What is interference?
100
This property of a wave is measured in Hertz.
What is frequency?
100
This type of wave travels through a medium as a longitudinal wave.
What is sound?
100
The energy heard when a plane flies faster than the speed of sound is called this.
What is a sonic boom?
200
Mechanical waves are classified according to this.
What is how they move?
200
This occurs when waves travel around barriers or squeeze through narrow openings and then spread out.
What is diffraction?
200
This is the ability of a material to bounce back after being disturbed.
What is elasticity?
200
A set of tones that when combined sounds pleasing to your ears.
What is music?
200
The fluid filled cavity in the ear that transmits signals through the auditory nerve to the brain
What is the cochlea?
300
This type of wave moves the mediium parallel to the direction of the disturbance.
What is a longitudinal wave?
300
This type of interference occurs when two waves meet to create a greater amplitude.
What is constructive interference?
300
When an incoming wave combines with a refelcted wave in such a way that the combined wave appears to be standing still the result is this.
What is a standing wave?
300
This refers to how well sound can be heard in a room or a hall.
What is acoustics?
300
Bats use this to navigate and locate their next meal.
What is echolocation?
400
This is an increase in the amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
What is resonance?
400
This is the measure from one corresponding wave part to another.
What is wavelength?
400
A person's high pitched voice has this type of frequency.
What is high frequency?
400
The most common cause of hearing loss is caused by this.
What is aging?
500
This is the bending of waves when they enter a new medium at an angle and change speed.
What is refraction?
500
The law of reflection states this.
What is the angle of incidence equals the angle of reflection?
500
Speed, wavelength, and frequency are related to one another by this mathematical formula.
What is speed = wavelength x frequency?
500
Sound waves with frequencies below human range (20,000)are called this.
What is infrasound?
500
This produces a picture of the inside of the human body using ultrasound waves.
What is a sonogram?
