Document Summary

Specular reflection is when light reflects on a smooth surface in a definite direction. Diffuse reflection is when light is reflected on a rough surface in different directions. The law of reflection states that the angle between the reflected ray and the normal vector is equal to the angle of incidence. Angle of reflection = angle of incidence. Real image is when the light rays actually emanate from the object. Virtual image is when light doesn"t emanate from the object and the image seems to be behind the mirror. A real image is when light rays converge after refraction. A virtual image is when light rays diverge after refraction. An upright image is above the x-axis = positive. An inverted image is below the x-axis = negative. Object distance: the distance at which the object is placed from the point of incidence on the mirror.

Which of the following statements are true concerning the reflection of light?

(a) For diffuse reflection, the angle of incidence is greater than the angle of reflection.

(b) The angle of incidence is equal to the angle of reflection only when a ray of light strikes a plane mirror.

(d) For specular reflection, the angle of incidence is less than the angle of reflection.

(e) The reflection of light from a smooth surface is called specular reflection.

1)A light ray is incident on a reflecting surface. If the light ray makes a 25° angle with respect to the normal to the surface, what is the exact angle (in degrees) made by the reflected ray relative to the normal?

2)The light ray that makes the angle θ1' is the refracted ray (true or false?)

3)True or False: The Law of Reflection can be used to show how an image appears behind a mirror and it can also be used to determine where the image will be located.

4) Snell's law is another name for the

law of refraction

5) A light ray incident on a block of glass makes an incident angle of 50.0° with the normal to the surface. The refracted ray in the block makes a 26.8° with the normal. What is the index of refraction of the glass?

A light ray traveling from a higher index of refraction medium into a lower index of refraction medium (for example, from water into the air) would bend away from the normal to the medium surface. When the refracted ray is parallel to the boundary of the medium, θ2= 90°. The incident angle, θ1, becomes θc, called the
