Specimen paper 3 physics imaging

Recommended Posts

Hello, 

I have doubts about answer to uestion 13 (a) (ii). As the image is formed at the near point, for overall magnification shouldn't the formula linear magnification of an eypiecie * linear magnification of an objective be used? And if they want to use angular maginifcation for an eyepiecie, why do they sue the formula for image at infinity (D/f) rather than imagie at the near point (1 + D/f)? I keep getting 429, whereas the answer apparently is 380??
