Answer: The correct answer is D) Point.
Point is represented by a dot, which has no width, length or height.
On the other hand, angle is a figure formed with the help of two rays, which share a common end point.
Line is a segment, which consists of two end points whereas ray is a part of line having only one end point. Therefore, angle, line, and ray all three have width or length.
Thus, the correct option is Point.
The given data is Magnification, M = 15
Length of the tube , L = 16 cm
The focal length of the lens can be calculated by:
M = L/F
Substituting the value, we get:
15 = 16/f
f = 16/15
f = 1.067 cm
Using the equation of magnification we get,
M = v/u
Substituting the values we get:
15 = v/u
v = 15 u
With the help of lens formula, calculate the object distance:
1/f = 1/v + 1/u
Substituting the value we get,
1/1.067 = 1/15u + 1/u
0.937 = 1.067/u
u = 1.13 cm or 1.1 cm.
Hence, the object distance is 1.1 cm.
