We are currently struggling to cover the operational costs of Xtremepapers, as a result we might have to shut this website down. Please donate if we have helped you and help make a difference in other students' lives!

Calculate the gradient of the straight line.
When incidence ray is greater than critical angle than what happens?The normals are in red and the rays are in green. For Ray 2 the angle of incidence and reflection must match what is given in the question. I've just drawn an estimate.
It gets reflected instead of refracted.When incidence ray is greater than critical angle than what happens?

Total Internal ReflectionWhen incidence ray is greater than critical angle than what happens?

explain it plz
NiceThat's what I have drawn.
Except the middle lines, make the others a bit curved but yeah the concept is correct.Correct?
Is type ke questions nae samaj ate.anyone explain me how to handle these type of questions..Except the middle lines, make the others a bit curved but yeah the concept is correct.
i think its answer is B
Can someone answer these doubts:
- What do we need to know about the Expansion of solids, liquids, gases topic?
- What are Capacitors? And what is a time delay circuit?
- Centripetal force? I can't find that anywhere in the book. =.=
- What are the ways of preventing heat loss in Homes?
- Do we need to know about Photocopies, Van De graff generators? How much is required?
- Can i skip Electronic systems? Is that a good idea?
- Do questions in Physics paper 2 repeat? What would be better, to read marking schemes, or to read the book?
- What is Linearity in a thermometer?
- And how to increase sensitivity. I know that it can be increased by decreasing the size of bore, but i also read somewhere it can be increased by increasing the volume of liquid in bulb? How does that work?
- Why should a switch and fuse be placed on the live wire?
- Diodes? What do we need to know about them?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
