What will cause the laser light to bend as it enters a ice cube?
I will cause it to refract.
What is the definition of refracted?
of Refract, Serving or tending to refract; as, a refracting medium.
Bending of light as it passes through water?
Yes, light bends as it enters water. This is known as refraction of light. It is the change in direction of a wave due to a change in it's speed. Water has an index of refraction of 1.333 and air has an index of refraction of 1.From Wikipedia:In optics, refraction occurs when light waves travel from a medium with a given refractive index to a medium with another. At the boundary between the media, the wave's phase velocity is altered, usually causing a change in direction. Its wavelength increases or decreases but its frequency remains constant. For example, a light ray will refract as it enters and leaves glass, assuming there is a change in refractive index. A ray traveling along the normal (perpendicular to the boundary) will change speed, but not direction.
How does a periscope work to refract light?
Periscopes work by reflecting light, not refracting it. Light enters the top of the periscope and is reflected through 90 degrees by either a plane mirror or a right angled prism (TIR) and travels down the tube where it is reflected again along the eyepiece to the eye.
When light refracts?
Because when light enters a new substance, its speed changes. In order for the law demonstrated in the equation (frequency = speed/wavelength) to remain the same, the wavelength of the light particle/wave must shorten or lengthen. This change causes the wave to slightly refract to one side or the other.
What will cause the laser light to bend as it enters a ice cube?
I will cause it to refract.
Which color of light enters the observers eye from rain drops higher up?
Colours which refract less.
Will light always bend when it changes medium?
Not always. It won't bend if it enters the new medium perpendicular to the surface that separates them, and it won't bend when the refractive indices of the two media are equal.

How do eyeglasses and contact lenses work?
They refract the light before it enters your eye the precise amount it needs adjusting to make the light hit your retina in the correct position.

Why a ray of light does not refract if it enters denser medium perpendiclarly?
Since the angle of incidence is zero the angle of refraction also has to be zero. Hence no refraction and it enters in the same direction. As we consider the concept of wave front, all the points on the wavefront would hit the glass surface at the same time and secondary wavelets would start at the same time and all of them travel with the same speed. So the common envelope to these secondary wavelets would be parallel to the incident plane wavefront. Hence no refraction.
