Question

Write your answers as T or F on the answer page. Any answers NOT recorded on the answer page will NOT be counted. Light is an electromagnetic wave that is longitudinal. T) True or F) False A convex mirror can be used to produce both real and virtual images. T) True or F) False If a spherical mirror has a positive focal length, it must concave. T) True or F) False The image produced by a spherical lens has a magnification +1.5, so the image must be real. T) True or F) False The equation: n_1sintheta_1 = n_2sintheta_2, is known as Brewster's Law. T) True or F) False In the diagram, the large arrow represents an object and the small arrow is the center of curvature of the mirror. This arrangement will produce an erect image to the right of the mirror that is and larger than the object. T) True or F) False The image produced by a magnifying glass is vertual. T) True or F) False Indexes of refraction are always greater than one! T) True or F) False

Explanation / Answer

1. False

light is transverse EM wave.

2. convex mirror always produces virtual images.

False

3. True .

4. magnification by a single spherical lens is positive then image will be virtual.

False

5. this snell's law
  
false

6. image is produced to the right of the mirror.

so mirror is convex mirror.

and convex mirror always produce diminished image. (so image can not be larger than object)

False

7. image that we see bymagnifying glass is not obtained on screen.

hence vertual image.

True

8. True
