Which of the following satisfies the condition for relation between wavelength and length of a pipe open at one end to obtain the first harmonic? ? = L/2 , L is length of tube and ? is the wavelength ? = 2L , L is length of tube and ? is the wavelength ? = 4L , L is length of tube and ? is the wavelength None of these.
Which of the following is correct regarding the energy in standing wave? Energy keeps decreasing Energy keeps increasing Energy remains same Energy has nothing to do with standing wave.
Speed of a wave is 340 m/s. Find its wavelength if frequency is 100 Hz. 0.34 m 0.034 m 34.0 m 3.40 m.
The speed of a wave is defined as the speed at which the particles of the wave vibrate. the speed of the medium through which the wave passes the speed of transfer of the energy of the wave the speed at which the vibrations of the wave are produced.
A source of sound moves directly towards a stationary observer. The frequency of the sound detected by the observer is different from the source frequency because the loudness of the sound increases as the source moves towards the observer the apparent wavelength of the sound is longer. the speed of sound relative to the observer is increased. the apparent wavelength of the sound is shorter.
A source of sound moves away from a stationary observer. The frequency of the sound detected by the observer is different from the source frequency because the loudness of the sound increases as the source moves towards the observer the apparent wavelength of the sound is longer the speed of sound relative to the observer is increased. the apparent wavelength of the sound is shorter.
When a wave crosses the boundary between two media, which one of the following properties of the wave does not change? Amplitude Wavelength Frequency Speed.
Electromagnetic waves are Transversal in nature Longitudinal in nature partial transversal and partial longitudinal None of these.
What is the difference related to harminics between one side open pipe and both side open pipe? A pipe open at one end produces all the harmonics while pipe open at both ends does not produce all the harmonics A pipe open at one end does not produce all the harmonics while pipe open at both ends produces all the harmonics There is no difference in harmonics between both.
The fundamental frequency of a pipe closed at one ened is F. a pipe of the same length but open at both ends has afundamental frequency of F/2 2F F 4F.
A light wave that is constrained to pass through a narrow aperture will spread out. This phenomena is known as interference reflection diffraction refraction.
To study diffraction we should use single slit device double slit device We do not need a device with slit to study diffraction None of these.
What happens to diffraction pattern if we use coloured light? The pattern is not visible The pattern has coloured fringes There is no change if we use white light instead of monochromatic light. None of these.
What is the difference between interference and diffraction? The relative intensity in diffraction keeps increasing The relative intensity in interference keeps increasing The relative intensity in diffarction keeps decreasing Intensity does not change in Interference.
What is the path difference in doule slit experiment for bright [maxima] fringe? It is even multiple of ?/2 It is odd multiple of ?/2 It is equal to ?/2 None of these.
