9.) An object of height 5 cm is placed 15 cm away from a convex mirror of focal length 20 cm. Find out the location of the image and magnification produced. What happens to the image if the object is moved

farther from the mirror?

10) A candle 5 cm in size is places at 30 cm in front of a concave mirror of radius of curvature 40 cm. At

what distance from the mirror should a screen be placed in order to obtain a sharp image? Describe the

nature and size of the image. If the candle is moved towards the mirror, how would the screen have to

be moved?

11) An object 2 cm in size is placed 30 cm in front of a concave mirror of focal length 15 cm. At what

distance from the mirror should a screen be placed in order to obtain a sharp image? What will be the

nature and the size of the image fanned? Draw a ray diagram to show the formation of the image in this

case

12) (a) To construct a ray diagram, we use two light rays which are so chosen that it is easy to know their

directions after reflection from the mirror. List these two rays and state the path of these rays after

reflection. Use these rays to locate the image of an object placed between center of curvature and focus

of a concave mirror

(b) Draw a ray diagram to show the formation of image of an object placed between the pole and

principal focus of a concave mirror. How will the nature and size of the image formed change, if the

mirror is replaced by converging lens of same focal length?

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.

An isolated conducting spherical shell carries a positive charge. part a which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? which statement (or statements) about the electric field and the electric potential inside and outside the spherical shell is correct? electric potential inside the shell is constant and outside the shell is changing as 1/r2 both the electric potential and the electric field does change with r inside and outside the spherical shell electric potential inside and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is equal to zero electric field inside and outside the shell is constant (does not change with the position r), but is not equal to zero electric field inside and outside the shell is changing as 1/r (where r is the distance from the center of the sphere) electric field inside is equal to zero and outside the shell is constant, but not zero electric potential inside the shell is constant and outside the shell is changing as 1/r electric field inside and outside the shell is changing as 1/r2 electric field inside is equal to zero and outside the shell is changing as 1/r2 electric field inside and outside the shell is zero electric field inside is constant and outside the shell is changing as 1/r
