Question
1. Light is an electromagnetic wave that is longitudinal A) True or B) False A convex mirror 2. can be used to produce both real and virtual images A) True or B) False 3. If a spherical mirror has a positive focal length, it must concave. A) True or B) False uced by a spherical lens has a magnification +1.5, so the image must be real. A) True or B) False 5. The equation: misine, nzsin02, is known as Brewster's Law A) True or B) False 6. 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. A) True or B) False 7· The image produced by a magnifying glass is vertual. A) True or B) False 8. Indexes of refraction are always greater than one! A) True or B) FalseExplanation / Answer
1. light is a transverse wave as the osccilating quantity osscilates perpendicular to the direction of motion
hence this statement is false
2. A convex mirror always produces virtual images
hence this statement is false
3. Spherical mirror with +ve focal lengths are convex mirrors
hence this statement is false
4. for m = +1.5
image is virtual ( as real images have -ve magnification)
hecne this statement is false
