State the general name of the waves in which the particles of the medium vibrate:
(i) in the same direction as wave.
(ii) at right angles to the direction of wave.

Academic Physics NCERT Class 9

(i). In longitudinal waves, the particles of the medium vibrate in the same direction as wave.

(ii). In Transverse waves, the particles of the medium vibrate at right angles to the direction of wave.

The longitudinal waves travel in a coiled spring at a rate of 4 m/s. The distance between two consecutive compressions is 20 cm. Find: (i) Wavelength of the wave (ii) Frequency of the wave
Draw the sketches of two waves A and B such that wave A has twice the wavelength and half the amplitude of wave B.
Which wave property determines the Pitch of sound?
Name the device which is used to reverse the direction of current in the coil of a motor?
The work done is zero ifa. The body shows displacement in the opposite direction of the force applied. b. The body shows displacement in the same direction as that of the force applied. c. The body shows a displacement in perpendicular direction to the force applied. d. The body masses obliquely to the direction of the force applied.
A T.V. Station transmits waves of wave length $200\ m$. Calculate the frequency of waves, if the speed of waves in air is $3.0\times10^{8}\ ms^{-1}$.

In the adjoining figure, identify$(i)$ the pairs of corresponding angles.$(ii)$ the pairs of alternate interior angles.$(iii)$ the pairs of interior angles on the same side of the transversal.$(iv)$ the vertically opposite angles."
Explain the term amplitude of a wave. Draw the diagram of a wave and mark its amplitude on it.
Represent graphically by two separate diagrams in each case$(i)$. Two sound waves having the same amplitude but different frequencies.$(ii)$. Two sound waves having the same frequency but different amplitudes.$(iii)$. Two sound waves having different amplitudes and also different wave lengths.
What is the time period of sound wave?
In which direction does the transfer of heat normally take place?
What does this line mean? the disturbance created by a source of sound in the medium travels through the medium and not the particles of the medium"."
