The waves in which particles of the medium vibrate perpendicular to the direction of waves are:
Electromagnetic waves
Sound waves
Both a and b
Transverse waves
the water waves after striking the hurdle will:
reflect
refract
diffract
all a b and c
When a body moves to and fro about a point, its motion is called:
Random motion
Vibratory motion
Linear motion
Rotatory motion
The water waves obey the laws of:
Reflection
Refraction
Diffraction
All of these
Time period is reciprocal of:
Frequency
Cycle
Wave-length
Amplitude
