Particles of the medium implement simple harmonic motion about their mean position in a direction perpendicular to the direction of propagation of wave motion.
(i) It goes in the form of crests and troughs.
(ii)A crest is a section of the phase which is raised temporarily above the normal position of rest of the particles of the medium when a transverse wave passes by it.
(iii) A trough is a part of the phase which is depressed temporarily below the normal position of rest of the particles of the medium, when transverse wave passes by it.
(iv) Examples of transverse wave motion: Movement of string of a sitar or violin,
Ultra violet Waves: The wavelength of ultra violet wave from 380mm down to 60nm.
Two forces P & 2P act on the particle if the first is doubled & the second enhanced by 20N.The direction of the resultant remains unchanged. What is the value of P.
