AI Thread Summary
A camera's design becomes wider or longer primarily to accommodate larger film or sensor sizes, which allows for capturing more detail and producing larger images. The relationship between lens size and image quality is influenced by diffraction; larger lenses minimize diffraction effects, enhancing image clarity. The confusion in the discussion stems from understanding how camera dimensions relate to image size and quality. Ultimately, a larger camera setup is essential for achieving higher resolution images. This design principle underscores the importance of lens and sensor size in photography.

Why does a camera get wider/longer?

The Attempt at a Solution



Well, I assume that it is to produce the largest image that can possibly be on the film. But I'm a little confused on the question as a whole? Am I on the right track and what can I add on to what I think thus far?

Thanks in advance for your help! It is totally appreciated!

It'sa little confusing, can you post the complete question?
 
If it is desirable to produce the large image, then why does the camera get wider/longer?

I agree, I'm not sure what the question is exactly asking! Thanks for your help thus far!
 
Not sure what it's asking but:
To make a large image you want a large negative, the minimum detail siaze on a film (or a CCD) is a fixed sizeso to get more detail/pixels you need bigger film (or CCD).

In a perfect camera you are limited by diffraction, the larger the lens the less the effect of diffraction
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
