00:00But good, the speed of wave is defined.
00:05The speed at which particle of the wave vibrates.
00:10The speed of the medium through which the wave passes.
00:15The speed of transfer of the energy of the wave.
00:20The speed at which the wave.
00:25The speed at which the waves are produced.
00:28So this is the right answer.
00:30The speed of transfer of the energy of the wave.
00:35The standing wave in an open pipe come about as a result of.
00:40Reflection and superposition.
00:42Reflection and diffraction.
00:45Superposition and diffraction.
00:47Reflection and refraction.
00:49This is correct.
00:50Reflection and superposition.
00:52Okay, in an interference.
00:55This is pattern.
00:56Bright fringes are wider than dark fringes.
00:59Dark fringes are wider than dark fringes.
01:00Bright fringes are wider than bright fringes.
01:02Both dark and bright fringes are equal.
01:05Bright fringes are wider than dark fringes are wider than dark fringes.
01:10to dancer medium is sufferer face change
01:15of 180 degree to obtain interference of light waves
01:20option A to obtain the source should be
01:25face coherent the source should be monochromatic
01:30the principle of superposition shall be applicable
01:35D option is all of above
01:37answer is all of above
01:38NAD
01:39Swipper questions
01:40Chapter of Optics
01:42So NAD
01:44Swipper
01:45The Erecting Lens in Terrors
01:50The Erecting Lens in Terrors
01:51The Erecting Lens in Terrors
01:52Increases magnification
01:54Decreases magnification
01:55has no effect on magnification
01:57So take a look at your mind
01:59One option is
02:00none of these
02:01but the correct answer
02:02has no effect on magnification
02:05A body who cannot see distant object is said to have a
02:10detect
02:11called
02:12Stegmination
02:15Contracted
02:16Of
02:17Hypermetropia
02:18So
02:19Hypermetropia
02:20Dash
02:21Dash
02:22is an eye defect
02:23in which a person cannot see the
02:25near object
02:26near object
02:27because the distance
02:28between eye
02:29and its rear reader
02:30is too short
02:31So
02:32short
02:33suddenness
02:34long
02:35suddenness
02:36spherical
02:35Scientists
02:36are
02:40Observer apparently change in the page of source.
02:45Due to the relative motion, the source and observation
02:50Observer is called Option A Resonance Vibration Effect
02:55Compton Effect, Dobbler Effect
02:57Of course, the answer will be Dobbler Effect

03:05negative again when source of sound moves towards a stationary
03:10listener there occur a decrease in frequency and in
03:15increase in wavelength no change in frequency
03:20answer and increase in frequency
03:23record what a 6 beats are produced
03:25as a result of diffraction, resonance, constructive and destructive
