Which one of the following can be polarized?
Example electromagnetic waves. Hence, X rays can be polarised. Sound waves in air travel parallel to the direction that the particles within it oscillate it therefore they are longitudinal in nature – it propagates in 1 dimensional direction so it can not be polarized.
Can heat waves be Polarised?
Complete step-by-step answer: The sound waves are longitudinal waves and therefore cannot be polarized. And the heat waves are transverse waves and therefore they can be polarized.
Which of the following waves can be Polarised I X rays II sound waves give reasons?
Solution : As only the transverse wave can be polarized, that is why the heat waves which are transverse wave and have vibrations perpndicular to the direction of propagation can be polarized whereas the sound waves cannot be polarized being longitudinal in nature and having vibrations in the direction of propagation.
How is the speed of EM waves in vacuum determined by electric and magnetic field?
Solution. The speed of the em-waves in vacuum is determined by the ratio of peak value of electric and magnetic fields.
Is the speed of electromagnetic waves in a vacuum?
Generally speaking, we say that light travels in waves, and all electromagnetic radiation travels at the same speed which is about 3.0 * 108 meters per second through a vacuum.
What are the seven types of electromagnetic radiation try listing in order of increasing frequency?
EM radiation is classified into types according to the frequency of the wave: these types include, in order of increasing frequency, radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
How is the speed of EM waves in vacuum?
An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c). The propagation of an electromagnetic wave through a material medium occurs at a net speed which is less than 3.00 x 108 m/s.
