My language is 'Sinhala'. Google doesn't support! Not that point reflection either! :( I'm asking when looking through a mirror, sides are flipped right? What is the physics term for that incident? Like, "Bending of light rays when passing through a surface between one transparent material and...

Thanks! But that's not what I'm looking for! :( something like 'flipping sides'??

Homework Statement I've done physics in a non-english medium and I want to know what is the technical term to call the incident where the image is flipped vertical through a mirror. I mean if we stand infront of a mirror and raise the right arm, the mirror image shows we're raising the left...

My bad. It's a convex lens :( Sorry, now only noticed. I think now you can get it correct. Thanks for the support. :) It was in my exam paper and I chose the wrong one anyway! :(

That makes sense. Because my level of knowledge is limited to the basic principles and i haven't used δf(x)/δx applications any where and that describes how few I know about this topic. :/ Thanks a lot for the support people.

Sorry, I think the image makes a little fuzzy. That arrow curve is perpendicular to the axis. In this image it looks it's headed towards i see.

I got an exam tomorrow and while i was studying, this popped in. Is there a gravitational potential inside a mass (eg : 500 km deep from the Earth surface)? We can calculate the Gravitational field intensity inside a mass by taking the distance from the center to that inner-point as x and...

Thanks, the answer is B. I marked it wrong anyway! :/

Homework Statement Find the correct image produced by the concave lens. F is focal length. Homework Equations If an object is placed between F and 2F, the image will be inverted, real, larger and beyond 2F. The Attempt at a Solution I choose the answer A. Is it correct? *Please...

Thanks for the help and the link! :D

Homework Statement Write an expression E for the average kinetic energy of Helium atoms using the Boltzmann constant. Homework Equations PV = nRT PV = \frac{1}{3}mN\overline{c^2} k = \frac{R}{N_A} [P - Pressure ; V - Volume ; m - Mass of an atom ; N - Number of atoms ; others have...

As atoms and compounds are always trying to minimize the instability! I guess other theories behind that are too much for me. I'm doing ALs. :) So I guess I won't be getting such in my MCQ paper! :D Thanks again!

So it's with the situation where you have to decide what's stronger relying on other facts. :D Thanks!

What is the most powerful bond? Hydrogen bond or Ion-dipole bond?

Yep. I got answers. Thank you all! :D
