Does water reflect or refract and why?
Both.Water is transparent to visible light but the speed of light in water is different to the speed of light in air. As a result, light rays travelling from air to water are usually refracted. However, as is the case at any interface between transparent media, light rays which hit the surface of the water at an angle greater than the critical angle are reflected.
What is the difference between refracted light and reflected light?
Refraction is the change in direction caused by a speed differential as light travels through different mediums, or temperature/pressure gradients. Reflection is light directly hitting an object and exiting at the same angle at which it hit.
Which travels at a greater speed light waves or sound waves?
Light Waves.
When a wave crosses a surface at an angle from one medium into another why does it pivot or turn as it moves across the boundary into the new medium?
The phenomenon you talk about is called "Refraction". You an find an explanation, with diagrams, in the Wikipedia article on "Refraction". Basically, the change of direction is related to the change in the speed of the wave.
What causes light rays to refract?
light travels in straight path and when speed of medium in which light travels change then it refract due to change in speed light rays bend and refract
Will the mass change at a very high speed compared the speed of light?
Yes. According to the extended theory of relativity, mass will increase as an objects speed increases. The closer the object's speed gets to the speed of light, the greater its mass will be and a greater force will be required to continue to accelerate it.
Is the speed of light changed when it is reflected back into the same medium?
No.
Is the speed of sound as speed of light?
The speed of light is much greater than the speed of sound.
Why the speed of electron beam is greater than the light speed in cathode ray oscilloscope?
Why is the speed of the electron beam greater than the speed of light in cathode ray oscilloscope.
Is the speed of light greater or lesser in air than in water?
The speed is the same. Light travels at a finite speed.

Why wavelenth changes with speed of light?
Wavelength does not change with the speed of light, nor does the speed of light change for different wave lengths. Wavelength x frequency = c (the speed of light) always for any given medium through which it travels. Greater wavelength yields lower frequency, so the speed is always the same. Speed changes as light passes into different media transparent to light, but the change in speed has nothing to do with any change in frequency or wavelength. Those are related only to the nature of the material and the particular light energies it may pass or absorb. So white light passing through a red filter emerges red because the blue and green frequencies have been absorbed by the filtering material. That change in wavelength and frequency is not related to any change in speed within the filter.

What is happening to a wave if it is being reflected?
when a wave is been reflected, the direction of the wave changes. The speed of a reflected wave depend on the material that caused the reflection, either it's an opaque, transluscent or transparent material. The speed of reflection is greater in the following ascending order. Transparent, transluscent and Opaque.
How does the speed of light in the fiber compare with the speed of light in the outer covering?
The speed of light in the fibre is greater. As a result, light moving toward the outer covering is refracted back towards the core.
How does the speed of light change as light change as light moves from a distant star toward earth in the vacuum of space?
As long as it remains in the vacuum in the vacuum, the speed of the light doesn't change at all.
