What is Amplitude?
A motion is its maximum displacement from equilibrium.

What are the different branches of Physics?
What is transverse wave,longitude waves and Surface Waves.
100
What is Amplitude ?
Amplitude: the height of the wave, measured in meters.

What are the Four Basic Properties of Sound?
We distinguish music from other sounds by recognizing the four main properties of musical sounds: pitch, dynamics (loudness or softness), tone color, and duration.

What are Light Waves ?
In this sense, gamma rays, X-rays, microwaves and radio waves are also light. Like all types of light, visible light is emitted and absorbed in tiny "packets" called photons and exhibits properties of both waves and particles.
200
number of waves that pass a given point per second
what is Frequency
200
What are Standing Waves?
a stationary wave, Is a wave in a medium in which each point on the axis of the wave has an associated constant amplitude.
200
What are the Properties of Waves ?
Amplitude, Wavelength, Period, Frequency and Speed.

What are the physical properties of sound?
Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude, or height, of sound waves. The greater the amplitude, the louder the sound perceived.

Explain the difference between Light and Transverse/Longitudinal Waves
Light and other types of electromagnetic radiation are transverse waves. Water waves and S waves (a type of seismic wave) are also transverse waves. In transverse waves, the vibrations are at right angles to the direction of travel.
300
Define Standing Wave?
wave that seems to be stationary
300
What is a good example of a Longitude wave
The displacement of the medium is parallel to the propagation of the wave.
300
What is the Formula for Wavelength?
wavelength = speed / frequency
300
What is the frequency of Sound?
The SI unit of audio frequency is the hertz (Hz). It is the property of sound that most determines pitch.
300
What is the amplitude of a light wave?
the intensity or brightness of the light relative to other light waves of the same wavelength. It's a measure of how much energy the wave carries.
400
What Is Virtual Image
a virtual image cannot be projected onto a screen
400
How can you tell the difference between a Traverse Wave and a Standing Wave ?
Traveling Waves vs. Standing Waves, A mechanical wave is a disturbance that is created by a vibrating object and subsequently travels through a medium from one location to another, transporting energy as it moves. As a wave is observed traveling through a medium, a crest is seen moving along from particle to particle.
400
What are the four characteristics of waves
Amplitude: the height of the wave, measured in meters. Wavelength: the distance between adjacent crests, measured in meters. Period: the time it takes for one complete wave to pass a given point, measured in seconds. Frequency: the number of complete waves that pass a point in one second, measured in inverse seconds, or Hertz.
400
How are the information characteristics of sound coded?
Physical Characteristics of Sound. Waves have three important characteristics: amplitude, wavelength, and frequency (frequency is described in units called hertz). Psychological Dimensions of Sound
400
What is a wave of light?
Each light wave has a series of high points known as crests, where the electric field is highest, and a series of low points known as troughs, where the electric field is lowest.
500
What Is Diffraction
bending of waves around a barrier or through an opening
500
How do we use longitudinal waves ?
The motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.
500
What are the characteristics of a Mechanical Wave?
A mechanical wave is a wave that is not capable of transmitting its energy through a vacuum. Mechanical waves require a medium in order to transport their energy from one location to another.
500
What are the Six Basic Properties of Sound?
The Six Basic Properties are, Frequency/Pitch Amplitude/Loudness Spectrum/Timbre Duration Envelope Location
500
What is light?
Light is a transverse, electromagnetic wave that can be seen by humans. The wave nature of light was first illustrated through experiments on diffraction and interference.
