MCQ
The expression of $Y$ in the above circuit is:
- A$\text{ABCD}$
- B$\text{A+BCD}$
- ✓$\text{A+B+C+D}$
- D$\text{AB+CD}$
✓
Answer
Correct option: C.
$\text{A+B+C+D}$
Here, to build the logic three $\text{OR}$ gates are used hence, all the input signals will be added to each other
Hence, the boolean expression is : $\text{A+B+C+D = Y}$
Hence, the boolean expression is : $\text{A+B+C+D = Y}$

$A$ concave mirror is placed on a horizontal surface and two thin uniform layers of different transparent liquids (which do not mix or interact) are formed on the reflecting surface. The refractive indices of the upper and lower liquids are $\mu_1$ and $\mu_2$ respectively. The bright point source at a height $‘d’$ ($d$ is very large in comparison to the thickness of the film) above the mirror coincides with its own final image.
