- (A), (B) and (C) Only
- (B), (C) and (D) Only
- (C), (D) and (E) Only
- (A), (D) and (E) Only
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
- (A) is incorrect because weight is not the amount of matter, it is the force due to gravity.
- (B) is incorrect because mass is the amount of matter, not the force exerted by gravity.
- (C) is correct as volume is indeed the space occupied by a substance.
- (D) is correct, temperatures below 0°C are possible, but in the Kelvin scale, 0 K is the absolute zero, so negative temperatures are not possible.
- (E) is correct, precision refers to how consistent multiple measurements are. Thus, the correct answer is (C), (D), and (E) only.
- (B) is incorrect because mass is the amount of matter, not the force exerted by gravity.
- (C) is correct as volume is indeed the space occupied by a substance.
- (D) is correct, temperatures below 0°C are possible, but in the Kelvin scale, 0 K is the absolute zero, so negative temperatures are not possible.
- (E) is correct, precision refers to how consistent multiple measurements are. Thus, the correct answer is (C), (D), and (E) only.

Two light beams fall on a transparent material block at point 1 and 2 with angle \( \theta_1 \) and \( \theta_2 \), respectively, as shown in the figure. After refraction, the beams intersect at point 3 which is exactly on the interface at the other end of the block. Given: the distance between 1 and 2, \( d = \frac{4}{3} \) cm and \( \theta_1 = \theta_2 = \cos^{-1} \left( \frac{n_2}{2n_1} \right) \), where \( n_2 \) is the refractive index of the block and \( n_1 \) is the refractive index of the outside medium, then the thickness of the block is …….. cm.
