Refraction is the phenomenon in which a wave changes direction as it moves from one medium to another, caused by a change in its speed due to changing mediums. This bending of the wave occurs because the wave changes speed at different points along the boundary between the two mediums.
The bending of a wave entering a new medium occurs because the wave changes speed when it goes from one medium to another, causing the wavefront to change direction. This change in speed leads to refraction, where the wave bends towards or away from the normal depending on the difference in the speeds of the two mediums.
Yes, the speed of a sound wave changes when it moves from one medium to another due to differences in the properties of the two mediums, such as density and elasticity. This change can result in phenomena like refraction or reflection of the sound wave at the boundary between the two mediums.
All waves carry energy away from their source through the movement of the wave disturbance. This energy transfer can occur through various mediums such as air, water, or even empty space for electromagnetic waves.
An ocean wave is classified as a surface wave because it travels along the interface between two mediums - air and water. The motion of the water particles decreases with depth, showing that the wave energy is confined to the water's surface. This distinguishes it from internal waves, which propagate beneath the water's surface.
