The answer depends on what on earth you mean by the "dirtier" of a wave.
The light bends when it passes from one medium to another. But only if it approaches the interface at an angle. In such a case it will still travel slower, but there will be no apparent bending.

When a light wave passes from a less dense to a more dense medium, such as air to glass, it slows down and bends towards the normal (an imaginary line perpendicular to the surface). This phenomenon is known as refraction. The change in speed and direction of the light wave is due to the change in the medium's refractive index.
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE

When a wave passes from a less dense medium to a more dense medium, it generally slows down and changes direction. This change in speed and direction is called refraction. The wave may also experience a change in wavelength and frequency.
When a wave passes from a less dense medium to a denser one, most of the wave energy is answer is reflected FALSE
When a wave passes from a less dense medium to a more dense medium, its speed decreases while its frequency remains unchanged. Additionally, the wave may also experience refraction, causing it to change direction.
True. When a wave passes from a less dense medium to a denser one, most of the wave energy is reflected back into the less dense medium, causing partial reflection and refraction of the wave.
Refraction occurs when light changes direction as it passes from one medium to another, such as from air to water. This bending of light is due to the change in speed of light as it enters a denser or less dense medium, causing the light rays to change direction.
slows down in denser mediums & speeds up in less dense ones this explains why ur voice is so high pitched when u inhale a less dense gas like helium & why sound is deep & distorted underwater.
Refraction is the bending of light when it passes from a dense medium to a differently dense medium. Light therefore finds it easier/more difficult to travel and the speed changes accordingly, which is why it bends.
