Electromagnetic waves require
Water as medium
Wood as medium
Air as medium
No medium to propagate
Which statement is wrong about light?
Can travel through vacuum
Cannot travel through vacuum
Considered as a ray or a wave
Shows reflection
For standing waves,
Energy is not transferred from particle to particle
Amplitude of vibration of particles is maximum at antinodes and minimum at nodes.
Wavelength of standing wave is same as that of the component wave.
All the above are correct
Stationary waves
Transport energy
Does not transport energy
Have nodes and antinodes
Both b and c
The high pressure region in a longitudinal wave is called
Amplitude
Condensation
Rare fraction
Frequency
Standing waves are formed on a string when interference occurs between two waves having
The same amplitude traveling in the same direction with no phase difference between them
The same amplitude traveling in the opposite direction with no phase difference between them
Different amplitudes traveling in the same direction
Different amplitudes traveling in the opposite direction
The rings or ripples produced on the surface of the water are examples for
Longitudinal waves
Surface waves
Electro magnetic waves
A wave is a mode of transference of
Energy
Atoms
Electrons
Ions
When a stationary wave is formed, its frequency is
Same as that of individual waves
Twice that of individual waves
Half that of individual waves
Independent of that of individual waves
Transverse and longitudinal waves travel with
Different speeds in the same medium
Same speed in same medium
Same speed in different media
All the above
