Question

7. A student very cautiously traces the path of a ray through a glass slab for different values of the angle
of incidence (angle i). He then measures the corresponding values of the angle of refraction (angle r) and the
angle of emergence (angle e) for every value of the angle of incidence. On analyzing these measurements
of angles, his conclusion would be.
(a) angle i > angle r > angle e
(b) ang i = ang e > ang r
(c) ang i<ang r< ang e
(d) ang i= ang e < ang r

Answer 1

Answer:

top of a tower of height 78.4m two stones are projected horizontally with 10m/s and 20m/s in opposite directions. on reaching the ground, their seperation is 1. 120 m 2. 100 m 3. 200 m 4. 150 m

Step-by-step explanation:

corresponding values of the angle of refraction (angle r) and the

angle of emergence (angle e) for every value of the angle of incidence. On analyzing these measurements

of angles, his conclusion would
