Positive Focal Length Image - Real, Diminished, Inverted and Smaller?

AI Thread Summary
A positive focal length image is characterized as real, diminished, and inverted. There is confusion regarding the terms "diminished" and "smaller," which are considered equivalent in this context. Both terms can be used interchangeably without affecting the meaning. In physics, either term is acceptable, so the choice between "smaller" or "diminished" is a matter of preference. Ultimately, clarity in communication is key, and both terms convey the same concept.

This is a simple wording confusion. On one question that I did, the property for a positive focal length image was Real, Diminished and Inverted. On another question of the same type, the property for a positive focal length image was Real, Inverted and Smaller.

So, my confusion is the Diminished and Smaller property. Are they both the same thing?

Yes.
 
Which one is more suitable in physics terms? Should I write Smaller or Diminished?

It doesn't matter, they are both equivalent.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
