yes , if the light travel from less density to more density the speed will decrease
, the direction will change depend on the entered angle

What will be the effect of incident ray of light striking a rough surface compared to the same rays striking a smooth surface?
If the surface is completely reflective then the angle at which the incident light leaves the surface will be different. For a rough surface the light would be scattered, whereas for a smooth surface they would reflect at the same angle the hit. If the surface isn't completely reflective then the angle and speed and which the light enters the object. For a rough surface the angles will random and based on the refractive index of the material. For a smooth surface they will be proportional to the sin of the angle times the refractive index.
What is meant by dispersion without deviation?
when a ray of light enters two specifically arranged prisms and disperese i.e. splits into characteristic colours without suffering any deviation inside the prisms(the magnitude of deviation for both the prisms is same and in opposite direction, so net deviation is zero); its called dispersion without deviation...
Could a scientist use a prism to separate light into the colors of the spectrum?
Yes, anyone can use a prism to separate light into the colors of the spectrum. It is, in fact, fairly simple to do. You simply place the prism into a beam of light and orient it so that the light beam enters on face at an angle, travels through the prism approximately parallel to a second face, and exits the third face at an angle similar to its angle of entry. The light beam will now be deflected by a total angle which depends on the refractive index of the material from which the prism is made.
What happens when you get baptized?
If you truly get baptized , the holy spirit enters you and you are filled with it.
How is that any line intersecting the interior of a given circle is a secant of that circle?
Any line that enters a circle (and is not a tangent) must cross its boundary twice; once to enter, once to exit. Since a secant is a line segment that joins two different points on a curve, such a line as above is a secant.
What is the change of direction when a wave enters a different medium called?
Refraction
Why does the ray not change direction when it enters the glass at A?
sublimation
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.
When a light wave enters into a medium of different optical density?
index of refraction ( or refractive index)
What happens when speed of light enters a new kind of medium?
When light passes from one medium to another with a different refractive index, andnot in a direction perpendicular to the boundary between the media, its speed changes.
When a ray enters or leaves a glassblock It may change direction?
I think its reflection.
What is the name given to the change in direction of the ray of light as it enters a prism?
Refraction
When light enters a different medium the amount that the light is bent as it enters the medium is determind by the medium's index of?
When light enters a different medium, the amount that the light is bent as it enters the medium is determined by the medium's index of..........=refraction
Why does a beam of light change direction when it enters water?
Because it slows down when entering water.
Why does the beam of light change direction when it enters the water?
Because it slows down when entering water.
What does the Refractive index of a material signify?
The refractive index of a material signifies how much light slows down when it enters that material compared to its speed in a vacuum. It is a measure of how much the material can bend or refract light rays. Different materials have different refractive indices, which can impact how light interacts with them, such as causing light to be bent when passing through a lens.
When light enters glass from air at an olique angle the wave crests change direction there new direction is what?
The angel of the light ray emerging is called "Angle of Deviation"
