Babu theorm or instruments pe focus karo

Prachi Jindal 6 years, 9 months ago

You must focus on theory only. Numericals come for 15-16 marks and formulaes too carry their own weightage. Try to learn them if possible to gain extra marks or else try focusing only on theory.

Suhani Rana? 6 years, 9 months ago

Theory because it cover 50 to 55 marks and numerical cover 15 to 20 marks

Start with section D first. Write all the formulaes and make the diagrams accordingly. For num. write given and the formula used and for conceptuals part 0.5 marks is awarded for reasoning so a short precise para would work

Rotational Analogue of Force

Sanskriti S 6 years, 9 months ago

moment of force; the measure of force which causes an object to rotate about an axis

Harsha Phansalkar 6 years, 9 months ago

When two equal forces with opposite magnitude act on the same body but on different points, they produce a couple and start rotating the body this coupling moment is known as torque

These r produced by heat bodies

Harsha Phansalkar 6 years, 9 months ago

The molecules of substances(specifically water ) easily absorb these waves and gain thermal energy thus infrared are called heat waves

Sanskriti S 6 years, 9 months ago

their absorption causes heating effect

Derivation of course...because derivation and theory consist around 55 marks in the paper whereas there are only 15-20 marks of numericals

Sanskriti S 6 years, 9 months ago

numericals carry max if 15-20 marks, better u focus on theory nd derivations 'cause numericals demand practice!! Well, it's just a suggestion.

We can derive it by using hygens principle i.e. Sin(i)/Sin(r) = u(constant)

Shivam Keshri 6 years, 9 months ago

Refer to NCERT part 2 ray optics for normal derivation and wave optics for derivation using huygens principle
