does refraction occur for both sound waves and light waves

Waves carry energy from one place to another Transverse and longitudinal waves, Seismic waves Problems involving wavelength, frequency and wave speed Sound waves in a medium Radio waves, light and X-rays, electrom..

Summary - WAVE is a form of disturbance, which travels through a material medium due to the repeated periodic motion of the particles of the medium about their position. Mechanical wave is a periodic disturbance, which requires a material medium for its propagation. Electromagne..

Sound as a Wave - A ringing bell, a thunderclap, laughter, and rock music are sounds that seem very different to us. However, all sounds are alike because they are waves. Let us understand how wave properties can be applied to sound..

Sound is the form of energy propagated as waves which our ears receiv..

Formation and propagation of a pulse along a slin..

Take points 1,2,3 on the given wavefront AB. The distance traveled by light in t secs will be 'ct' where c is the velocity of light. With point 1 as centre and ct as radius, draw a sphere as shown (dotted circles). Repeat for points 2 and 3 and so on. Now draw a surface A 1 B 1 ..

In a liquid, the motion of the particles may be neither purely transverse nor purely longitudinal, but a combination of the two. The path followed by the particles is either a circle or an ellipse. The paths of several selected particles, their positions and the shape of the wave are sho..

Introduction - In the previous chapters we studied the different types of motion like uniform motion, accelerated motion, projectile motion and periodic motion. We then learnt to relate the acceleration of the body to the force applied. In this chapter we shall study the motion of collection of par..
