Category 1
The high point of a transverse wave is known as this.
What is a crest?
The bending of a wave that as it passes around a barrier
What is diffraction?
A repeating disturbance that transfers energy through matter or space.
What is wave?
When waves add together after arriving at the same place at the same time is known as this.
What is constructive interference?
When studying the law of reflection, the beam that bounces off the mirror is called this.
What is the reflected beam?
The less dense region of a compression wave is called this
what is a rarefaction?
When waves continuously interfere with each other it is known as this.
What is interference?
The lowest point of a wave is known as this.
What is a trough?
When waves subtract from each other when they overlap this occurs.
What is destructive interference?
When surfaces reflect sound waves, these occur.
What are echoes?
The number of wavelengths that pass a fixed point each second is considered this piece of data from a wave.
What is the frequency?
A material that through which a wave transfers energy is known as this.
What is a medium?
The distance between one point on a wave and the nearest point just like it is known as this.
What is a wavelength?
frequency is measured in this unit
What is Hz.(hertz)
According to the law of reflection, the angle of incidence is always equal to the
angle of reflection
The measure of the energy of a wave us known as this.
What is amplitude?
The bending of a wave as it moves from one medium to another
What is refraction?
the bending of a wave around an object like ocean waves bypassing an island is known as this.
What is diffraction?
When studying the Law of reflection, the light beam that strikes the mirror is known as this.
What is the incident beam?
This is the speed of sound
What is 340 m/s?
When matter moves in the same direction as a wave travels it is considered this.
What is longitudinal wave?
The ability of an object to vibrate by absorbing energy at its natural frequency is known as this.
What is resonance?
This is the formula for calculating wave speed.
Velocity=frequency(wavelength)
The line drawn perpendicular to the surface of the mirror in the law of reflection is known as this.
What is the normal?
A material that can bend light waves completely around an area, causing an area to be invisible is known as these.
What are metamaterials?
