Reflexión de la luz: espejos e imágenes

1. 1For reflection off a plane mirror, the angle of incidence

   1. Ais greater than the angle of reflection
   2. Bis less than the angle of reflection
   3. Cequals the angle of reflection
   4. Dchanges the angle of reflection
2. 2What is the angle of reflection?

   1. Aan angle that the incident ray makes with a line drawn perpendicular to the reflecting surface
   2. Ban angle that the reflected ray makes with a line drawn perpendicular to the reflecting surface
   3. Cthe angle the reflecting surface makes with the ground
   4. Dthe angle that the reflected ray makes with the incident ray
3. 3The law of reflection states that if the angle of incidence is 45 degrees, the angle of reflection is

   1. A90 degrees
   2. B22.5 degrees
   3. C45 degrees
   4. D135 degrees
4. 4A mirror with a flat surface is a

   1. Aplane mirror
   2. Bconvex mirror
   3. Cconcave mirror
   4. Dvirtual mirror
5. 5In a plane mirror, reflected light rays appear from

   1. Ain front of the mirror
   2. Ban angle above the mirror
   3. Ca distance behind the observer
   4. Dbehind the mirror
6. 6Unlike a virtual image, a real image

   1. Aforms at the curvature of a reflecting surface
   2. Bcan be viewed on a screen
   3. Ccannot be viewed on a screen
   4. Dis always upright
7. 7What is the point called at which the reflected rays intersect in figure 19-1?

   1. Avirtual image
   2. Bplane image
   3. Cfocal point
   4. Dilluminated point
8. 8A convex mirror can form

   1. Aboth virtual and real images
   2. Bonly real images
   3. Conly virtual images
   4. Dnone of the above
9. 9Why do plane mirrors and convex mirrors form only virtual images?

   1. Abecause they only reflect light
   2. Bbecause they cannot make light rays converge
   3. Cbecause the focal point is in front of the mirror
   4. Dbecause they both show a wide angle of view
10. 10Light refracts when it

    1. Abounces off a surface
    2. Bchanges speed
    3. Ccomes from a laser
    4. Dspreads out from its source
