The waves in which the particles of the medium vibrate in a direction perpendicular to the direction of wave motion are known as

When a wave moves in the direction of the vibrating Particles, it is called a longitudinal wave.

Given below are some examples of wave motion. State in each case if the wave motion is transverse, longitudinal or a combination of both (i) Motion of a kink in a long coil spring, produced by displacing one end of the spring sideways. (ii) Waves produced in a cylinder containing a liquid, by moving its piston back and forth. (iii) Waves produced by a motor-boar sailing in water. (iv) Light waves travelling from the sun to the earth. (v) Ultrasonic waves in air, produced by a vibrating quartz crystal.

A : The direction of a light is always perpendicular to wavefront R : A ray of light is a line perpendicular to a wavefront in the direction of propagation.

Given below are some examples of wave motion. State in each case if the wave motion is transverse, longitudinal or a combination of both. (a) Motion of kink in a longitudinal spring produced by displacing one end of the spring sideways. (b) Waves produced in a cylinder containing a liquid by moving its piston back and forth. (c ) Waves produced by a motorboat sailing in water. (d) Ultrasonic waves in air produced by a vibrating quartz crystal.

A wave is represented by the equation y = A sin (10 pi x + 15 pi t + pi//3) Where x is in metre and t is in second. a wave travelling in the positive x-direction with a velocity of 1.5 m/s a wave travelling in the negative x-direction with a velocity 1.5 m/s a wave travelling in the negative x-direction with a wavelength of 0.2 m a wave travelling in the positive x-direction with a wavelength 0.2 m

Two sound waves moves in the same direction in the same medium. The pressure amplutides of the waves are equal but the wavelength of the first wave is double the second. Let the average power transmitted across a cross section by the first wave be P_1 and that by the second wave be P_2 then.

Given below are some examples of wave motion. State in each case, if the wave motion is transverse, longitudinal or a combination of both? (i) Motion of a kink in a long coil spring produced by displacing one end of spring side ways. (ii) Waves produed in a cylinder containing a liquid by moving its piston back and forth. (iii) Waves produed by a motor boat sailing in water. (iv) Light waves travelling from sun to earth. (v) ultrasonic waves in air produced by a vibrating quartz crystal.

Assertion In electromagnetic wave, if direction of veriations of electric and magnetic field are perpendicular to each other and also perpendicular to the direction of wave propagation. Reason Electronegative waves are transverse in nature.

If E and B represent electric and magnetic field vectors of the electromagnetic wave, the direction of propagation of eletromagnetic wave is along.
