Calculate the focal length ofa reading glass of a person if his distance of ditinct visionis 75cm
To calculate the focal length of a reading glass (convex lens), we can use the lens formula:
1/f = 1/v - 1/u
Given:
v = -75 cm (distance of distinct vision, negative because it's on the same side as the object)
u = -25 cm (normal near point, assume)
However, since the normal near point is not given, we'll use the formula for a simple magnifier:
f = D / (D/d - 1)
where D = 25 cm (normal near point) and d = 75 cm (distance of distinct vision)
f = 25 / (75/25 - 1)
f = 25 / (3 - 1)
f = 25 / 2
f = 37.5 cm
The focal length of the reading glass is 37.5 cm.
I applied for AME CET 2025, but now when I am reading the reviews on the exam, I am getting tensed by the fact that this exam is fake and its a scam. Can somebody who gave the previous year exams tell me their experiences on this?
Hello,
It's completely normal to feel a bit anxious after reading mixed reviews online. However, AME CET (Aircraft Maintenance Engineering Common Entrance Test) is a recognized exam for admission to various AME institutes. It's not a scam, but like any other exam, there can be some negative experiences shared by candidates.
Hope it helps !
