Hi Can Someone Pls Answer The Question Number 2 Pls I Srsly Need It Thank U class=

Sagot :

Answer:1,0.95cm

2,21.82cms

3, 2.73

Explanation:

1,Its equation is following: 1o + 1i = 1f

1i = 1f - 1o

1i = 1−11 - 125

i = -7.64 cm - the image distance from the lens. The negative sign means that the image virtuali

h = 3.1* 7.6425 = 0.95 cm - the diameter of the coin’s imageimage

2,Use the lens equation to determine the image distance: 1/25 = 1/80 + 1/Di →

Di = 36.36 cm.

The image is real and on the opposite side of the lens as compared to the object.

The distance between object and image then is: 80 + 36.36 = 116.36 cm.

3,1/V+1/U =1/F ; 1/V =1/F-1/U ;- 1/15–1/48 =16-5/ 240 = 11/240 ; V =240/11

=21.82 CMS

IMAGE MAGNIFICATION V /U =21.82/48= 0.0.4546INVERTED

6 * 0.4546=2.7276 ≈2.73
