5 Wave Motion And Sound Flashcards
A wave in which the vibrations are parallel , or along, the direction on travel
Longitudinal
A wave in which the vibrations are perpendicular, or along, the direction of travel
Transverse wave
Tube closed at one , what happened?
Antinode at the open end,
Node at the closed end
Antinode - point where continuous vibration of maximum amplitude occurs
Node- the point which there is no displacement
Sinsusodial wave of a period 10 microseconds , it’s frequency is
100 KHz
Noise cancelling headphones operate of the principle by
Constructive interference of sound waves
Destructive inference of sound waves
Destructive inference of sound waves
Intensity of sound waves
Varies inversely as the square of distance from source
Increasing amplitude increases
Increasing frequency increase
Loudness
Pitch
Speed of sound in air at 0 degrees
Speed of sound at the std atmosphere temp and pressure is
M/s
331m/s
340 m/s
The name given to sounds below which a human ear can hear? 20hz
Infra sound
As temp increases, the speed of sound
Rises
With respect to simple harmonic motion, amplitude is defined as the
Distance of the highest or lowest point of the motion from the central position
When the movement of an object rotating around a radius at a constant speed is projected onto a plane, the projected image follows what path?
Sinusiodal
Wavelength is
Distance between crests
Two pure tones of similar frequency are heard by a person, what will they hear?
A beat of two tones
Two sound waves are the same but slightly out of phase . This means that
There will be no beat frequency.
