Then collect all problems from last five years question papers and practice them too. This much will be sufficient. Practice all problems from text book including the additional problems of NCERT.

If light is travelling from one transparent medium to another, its speed and wavelength changes but the frequency remains unchanged.

I made equations as follows - for mass , m1 --> T - m1g = m1a1 for mass , m2 --> T/2 - m2g = m2(a1 - a2 ) for mass , m3--> m3g - T/2 = m3(a1 + a2) but in the solution only my 2nd equation is correct.. mass m1 is going up so it should be T - m1g = m1a1 .. , right ?? and m3 is going down..... but in sol they have marked its acc. upwards... why so ??? I have problem in Chap-5 , Ques 28.
I made equations as follows -

for mass , m1 –>
T – m1g = m1a1

for mass , m2 –>
T/2 – m2g = m2(a1 – a2 )

for mass , m3–>
m3g – T/2 = m3(a1 + a2)

but in the solution only my 2nd equation is correct..
mass m1 is going up so it should be T – m1g = m1a1 .. , right ??
and m3 is going down….. but in sol they have marked its acc. upwards… why so ???
