Question
10) Single concave spherical mirrors produce images that A) are always smaller than the actual object. B) are always larger than the actual object. C) are always the same size as the actual object. D) could be smaller than, larger than, or the same size as the actual object, depending on the placement of the object. E) 3re always real. 11) Which statements about images are correct? (There could be more than one correct choice) A) A virtual image cannot be formed on a screen. B) A virtual image cannot be viewed by the unaided eye. C) A virtual image cannot be photographed. D) A real image must be erect. irrors always produce real images because they reflect light. 12) If a object is placed between a convex lens and its focal point, the image formed is A) virtual and upright. B) virtual and inverted. C) real and upright. real and inverted. 13) Which of following statements about the image formed by a single diverging lens are true? (There are more than one correct choice.) The image is always real. B) The image is always virtual. C) The image is always inverted D) The image is always upright. E) The image is always smaller than the object 14) A nearsighted person has a far point of 18 cm. What power contact lenses will allow this person to comfortably see distant objects clearly? A) +5.6 diopters B)-5.6 diopters C) +0.056 diopters 00 o D)-0.056 dioptersExplanation / Answer
Ans 10) single concave spherical mirrors produce images
that could be smaller than , larger than , or same size as of object depend on placement of object
Ans 11) a real image must be erect
Ans 12) if an object is placed between convex lens and focal point
image formed is real and inverted
Ans 13) image formed by single diverging lens
b) virtual d) upright e) smaller than the object
Ans 14) 1/f = 1/v - 1/u
=> 1/f = 1/infinite - 1/0.18
=> 1/f = - 5.6 diopter (b)
