refraction in a wave

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, electromagnetic waves..

Refraction of Light In general, if a ray of light is passing from medium 1 to medium 2, then If the medium 1 is air or vacuum, the refractive index of medium 2 is referred to as the absolute refractive index. The refractive index of a medium depends on the fo..

Sky waves are the AM radio waves, which are received after being reflected from the ionosphere. The propagation of radio wave signals from one point to another via reflection from ionosphere is known as sky wave propagation. The sky wave propagatio..

Wave motion is the propagation of a disturbance produced in a medium by the repeated periodic motion of the particles of the medium. It is only the energy of the disturbance that moves forward without any mass transfer. In an elastic medium, the frequency and the amplitude of osci..

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 and A 2 B 2 such tha..

As the wave is refracted, it is bent down gradually rather than sharply. However, below the ionised layer, the incident and refracted rays follow paths that are exactly the same as they would have been if reflection had taken place from a surface located at a gre..

Like light, sound waves also obey the laws of reflection and refraction. For sound waves to reflect, we need extended surface or obstacle of large size. For example, the rolling of thunder is due to successive reflections from clouds and land surfac..
