Thank you gneill, but I want to clarify my doubts: the thing is that one light ray travels downwards and the other upwards from the top extremity of the object to meet the convex lens. The website you suggested doesn't give a ray diagram that has a light ray traveling upwards from the object...

Thank you but, doesn't the refractive index involves Snell's law?

Homework Statement [FONT="Century Gothic"]Question [FONT="Century Gothic"]Given that the speed of light in a vacuum is 3.0 x 10^8 ms^-1, calculate the speed of light in a diamond of refractive index 2.4. Homework Equations - 3. Attempt So if the refractive index is 2.4, which means 2.4 =...

Plato is a philosopher, and sometimes he did went overboard. 'Atlantis' is probably apocryphal. Hitler thought that Aryans were the descendants of Atlantis' natives, so Aryans are viewed as superior (that's chauvinism, and Hitler is saying that because he has nothing to corroborate that Aryans...

My answer is: it is the relationship between the angle of incidence and the angle of refraction. Is it correct? If not, what should be the correct answer?

Ray diagrams (lenses) urgent problem. I need full explanations. 1. The question An object of height 2cm is placed 15 cm from a thin converging lens of focal length 10cm. Complete the paths of two rays on the figure to show their passage through the lens to the image formed. 2. The...
