Answer:

1) answer=virtual image.

2) Answer=When an object is placed behind the center of curvature, a real image is formed between the center of curvature and focus. The size of the image is smaller as compared to that of the object.

3) answer=

At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror; this line is known as a normal line. ... The angle between the reflected ray and the normal is known as the angle of reflection, qr.

4) answer=same

5) answer=it is of same size of the object.

thankyou
