Light slows down when it goes from a less dense material to a more dense material.
Draw yourself a diagram:
- Air on the top; water underneath. (a horizontal line separates the two phases)
- Draw a perpendicular line, this is a line at right angles to the interface between the two phases. This line is called the normal angle.
- Now draw a straight line arrow at an angle that goes from the air into the water and strikes the water at exactly the same point as the normal does.
- This is called the incident ray. It will not go straight but will bend towards the normal in the denser medium.
In summary:
The diagram consists of three lines - horizontal line separating the phases; a vertical line called the normal; the incident ray that strikes the horizontal line at the same point as the normal but will change angle at that point. The angle is smaller with the normal than what it would have been if there had not been a change in density.

lower one, (lower speed to higher speed), it's bent away from the normal.

If a beam of light strikes a diamond at an angle of 45 degrees what is the angle of refraction?
17° to the normal.
What are the terms related to refraction of light?
terms realated to refraction of light are * interface * incident ray * refracted ray * point of incidence *normal *angle of incidence * angle of refraction *angle of deviation
What is the angle between the normal and the surface of a mirror?
The angle between the normal and the surface of anything is by definition always 90 degrees, regardless of whether it is a mirror, a piece of concrete, a wooden plank, etc.
The bending of light as it passes into a transparent material of different optical intensity is known as?
Refraction: light speeding up and slowing down, between mediums. When light travels from a more dense material to a low density material like glass to air, light will be refracted away from the normal. When light travels from a less dense material to high density material, for example from air to water, light will be refracted towards the normal. Similarly, the refracted ray is a ray that shows the direction that light travels after it has crossed over the boundary. In the diagram, a normal line is drawn to the surface at the point of incidence. This line is always drawn perpendicular to the boundary. The angle that the incident ray makes with the normal line is referred to as the angle of incidence. Similarly, the angle that the refracted ray makes with the normal line is referred to as the angle of refraction. The angle of incidence and angle of refraction are denoted by the following symbols: = angle of incidence = angle of refraction --- = Normal 90'
Is there a pattern that describes the path of light during refraction?
Yes, Light bends towards the normal when it travels from air to another medium and bends away when going into air from another medium. This can be affected by the angle of incidence and what angle it is.
When light moves from glass into air at an angle is the light refracted toward or away from the normal?
it bends
What is the incident angle of a beam of light if the beam of light is reflected at an angle of 15 degrees from the normal?
15 degrees from the normal - on the other side.
The angle that the reflected light ray makes with the normal is called the angle of?
The angle of incidence
What is angle of incidence of light?
The angle made by the incident ray with the normal is called the angle of incidence.
What is the angle called when the reflected light rays make with the normal?
The angle is called the reflected angle.
What is the angle called that the reflected light makes with the normal?
Angle of reflection. Simple as that!
As a ray of light passes from air into glass the angle it makes with the surface normal will?
REFLECTION... (this is the right answer for: A ray of light strikes a flat surface of water. The angle that the reflected light ray makes with the normal is called the angle of? )if not incident ray.
When light rays enter a medium at an angle they?
The light rays will refract towards the normal of the medium and emerge out at the same angle.
What are angle of reflection and angle of incidence?
The angle of incidence is the angle between the incident ray of radiation (usually light) and the normal (perpendicular) at the point of incidence. Similarly, the angle of reflection is the angle between the reflected ray and the normal.
What happen to light rays as it strikes a smooth and shiny surface liike mirror?
The light rays gets reflected in the same angle. Angle between normal and the incident ray is called angle of incident and angle between normal and reflected ray is called angle of relection. Normal is an imagenary perpendicular line on the reflecting surface. Angle of incidence is alway equal to angle of reflection.
If a beam of light strikes a diamond at an angle of 45 degrees what is the angle of refraction?
17° to the normal.
What is the light ray that travels toward a reflective surface?
normal
