10th Class Physics MCQS
The waves in which particles of the medium vibrate perpendicular to the directions waves are:
Sound waves
bothe a and b
Transverse waves
Electromagnetic waves
The product of frequency (f) and wavelength? is equal to:
Wave speed
Amplitude
Time period
Wave energy / frequency
The part of waves at which particles of the medium are below the normal position are called:
Trough
Extreme positon
Crest
None of these
The waves, which are used to detect the broken bones, are called:
x-rays
Sound waves
Light waves
both b,c,
The unit of frequency is:
Heartz
Cycle per second
all a, b, c
Vibration per second
During S.H.M acceleration of the body is maximum at:
Mean position
Between mean & Extereme
None of these
Extreme positions
In a vacuum all electromagnetic waves have the same:
frequency
amplitude
Speed
wavelength
Which is not a hardware:
Mouse
Window
CPU
Keyboard
The formula of time period of simple pendulum is:
T = 1/2? ?L/g
T = 2??1/g
T = 2? (L/g)
T = 2? ?L/g
The instrument used to study the properties of waves is called:
Ripple tank
Stroboscope
None of these
Pendulum
