    I don't think you'll be worse than me. I was a student who got passing marks in Physics. But after mid-terms this year, I started to pay attention. Last test I got 42/70. Bottom line, meri lg gyi thi mgr maine wapsi ki! How? Well, study selected chapters (i skipped AC and a few topics of magnetism), go through Arihant Chapterwise Solutions (2018-2009) (i can't tell how much this book helped me ?) and yes, NCERT too — afterall it's the holy book for students. And you guessed it right by now, my english is good! ? (P.S. Any student that reads this, lg jao abhi se, hamare paas samay h abhi, sbki lga denge. Attitude and Approach is everything!)

    Because in mirror , there is a backwad polish coating of silver . That's why all light get reflected and we get a good image due to good intersection of light.

    Light is EM wave . It requires magnetic field and electric field to propagate. It has property to penetrate glass object having 1.45 mu . Refraction property occur. But and silver coated there occurs only reflection.

    as we increase temperature the electrons inside the conductor get thermal energy and start to move in zigzag motion that's why it's resistivity get increased.

    If you want to compare the emf of two cells, then for a wire having uniform area of cross section and uniform composition, the potential drop is directly proportional to the length of wire.

    Wrong reading Because voltage can be determined in parallel combination as it's constant there hence voltmeter must be connected in parallel Whereas, Current is determined in series therefore ammeter must be connected in series . Also we know in parallel due to less resistance , ammeter will allow more current to pass due to which it can suffer shot circuit. ?? nice question

    Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance . This capacity produces interesting and potentially useful effects. For a material to behave as a superconductor, low temperatures are required. Superconductivity was first observed in 1911 by H. K. Onnes, a Dutch physicist.

    Drift velocity per unit applied electric field is known as the mobility of charge carriers in a conductor.
    Mathematically,
    Mobility = Drift velocity / Electric field = Vd/E
    SI unit of mobility = m2V-1s_1 or Ms-1N-1C

    The principle of superposition of waves

    • Principle of superposition of waves describes how the individual waveforms can be algebraically added to determine the net waveform.
    • Waveform tells about the overall motion of the wave.It does not tell about individual particles of the wave.
