MCQ
Zener diode is used for:
  • A
    Amplification
  • B
    Rectification
  • Stabilisation
  • D
    All of the above

Answer

Correct option: C.
Stabilisation
A zener diode is always operated in its reverse biased condition. A voltage regulator circuit can be designed using a zener diode to maintain a constant $DC$ output voltage across the load in spite of variations in the input voltage or changes in the load current. The zener voltage regulator consists of a current limiting resistor $RS$​ connected in series with the input voltage $VS$​ with the zener diode connected in parallel with the load $RL$ in this reverse biased condition.Hence we can say that ,zener diode is used for stabilization.

Which of the following statements about the behaviour of light is not correct?
A person lives in a high-rise building on the bank of a river $50\, m$ wide. Across the river is a well lit tower of height $40\, m$. When the person, who is at a height of $10\, m$, looks through a polarizer at an appropriate angle at light of the tower reflecting from the river surface, he notes that intensity of light coming from distance $X$ from his building is the least and this corresponds to the light coming from light bulbs at height $'Y'$ on the tower. The values of $X$ and $Y$ are respectively close to (refractive index of water $  \simeq  \frac{4}{3})$
