Answer:
1. The image of the person is 1.41 m, virtual and formed at the back of the surface of the globe.
2. The person's image is 3.38 m tall.
Explanation:
From the given question, object distance, u = 0.75 m, object height = 1.8 m, radius of curvature of the reflecting globe, r = 8 cm = 0.08 m.
f = =
= 0.04 m
1. The image distance, v, can be determined by applying mirror formula:
=
+
=
+
-
=
=
= -
⇒ v = -
= - 1.41 m
The image of the person is 1.41 m, virtual and formed at the back of the surface of the globe.
2. =
=
v =
= 3.384
v = 3.38 m
The person's image is 3.38 m tall.
