Q:

Answer the following Program

#define CHARSIZE 8

#define MASK(y) (1 << y % CHARSIZE)

#define BITSLOT (y) (y / CHARSIZE)

#define SET(x,y) ( x[BITSLOT(y)] = MASK(y) )

#define TEST(x,y) ( x[BITSLOT(y)] & MASK(y) )

#define NUMSLOTS(n) ((n + CHARSIZE - 1) / CHARSIZE)

 

Give the above macros how would you

1. declare an array arr of 50 bits

2. put the 20th bit on

3. test whether the 40th bit is on or off

Answer

Q:

Refractive Index of glass with respect to water is

A) 4/3 B) 9/8
C) 2/3 D) 8/9
 
Answer & Explanation Answer: D) 8/9

Explanation:

Refractive Index of glass with respect to water can be calculated by 

(Refractive Index of glass with respect to air) × (1/Refractive Index of water with respect to air)

 

We know that,

Refractive Index of glass with respect to air = 4/3

Refractive index of water with respect to air = 3/2

 

Hence, Refractive Index of glass with respect to water = (4/3) x (2/3) = 8/9.
