Sample Question 1
Waves, Oscillations & Optics
EASY • Physics (Secondary & College Level)
What is the time period T of a simple pendulum of length L in a gravitational field g for small angular displacements?
A
T = 2 * pi * sqrt(L / g)
B
T = 2 * pi * sqrt(g / L)
C
T = pi * sqrt(L * g)
D
T = 2 * pi * (L / g)
✓ Correct Answer: A - T = 2 * pi * sqrt(L / g)
📖 Step-by-Step Solution & Conceptual Rationale:
The period of a simple pendulum is T = 2*pi*sqrt(L/g), independent of the mass of the bob.
Sample Question 2
Waves, Oscillations & Optics
EASY • Physics (Secondary & College Level)
When light travels from an optically denser medium (refractive index n1) into a rarer medium (n2) at an angle of incidence greater than the critical angle, what phenomenon occurs?
A
Total Internal Reflection
B
Polarization by Scattering
C
Diffraction
D
Refraction towards the normal
✓ Correct Answer: A - Total Internal Reflection
📖 Step-by-Step Solution & Conceptual Rationale:
Total internal reflection occurs when light strikes a boundary with a rarer medium at an angle exceeding critical angle theta_c = arcsin(n2/n1).
Sample Question 3
Waves, Oscillations & Optics
MEDIUM • Physics (Secondary & College Level)
In Young's Double-Slit Experiment, what is the fringe width (fringe spacing beta) on a screen at distance D for light of wavelength lambda with slit separation d?
A
beta = (lambda * D) / d
B
beta = (lambda * d) / D
C
beta = (d * D) / lambda
D
beta = lambda / (d * D)
✓ Correct Answer: A - beta = (lambda * D) / d
📖 Step-by-Step Solution & Conceptual Rationale:
Fringe spacing beta = lambda * D / d.
Sample Question 4
Waves, Oscillations & Optics
EASY • Physics (Secondary & College Level)
When a body moves with uniform velocity in a circle, its acceleration is directed:
A
Zero
B
Tangentially forward
C
Away from the center
D
Towards the center of the circle
✓ Correct Answer: D - Towards the center of the circle
📖 Step-by-Step Solution & Conceptual Rationale:
Centripetal acceleration is always directed radially inward towards the center of curvature.
Sample Question 5
Waves, Oscillations & Optics
EASY • Physics (Secondary & College Level)
Escape velocity from the surface of Earth is approximately equal to:
A
7.9 km/s
B
11.2 km/s
C
9.8 km/s
D
15.0 km/s
✓ Correct Answer: B - 11.2 km/s
📖 Step-by-Step Solution & Conceptual Rationale:
v_escape = sqrt(2*g*R) = sqrt(2 * 9.8 * 6.4x10^6) ≈ 11.2 km/s.
Sample Question 6
Waves, Oscillations & Optics
MEDIUM • Physics (Secondary & College Level)
In classical mechanics problem #16: In an elastic collision in one dimension between two identical masses where one is initially at rest, what occurs after collision?
A
Both stop immediately
B
Both masses stick together and move with half velocity
C

D
The incident mass stops and target mass moves with original velocity
✓ Correct Answer: D - The incident mass stops and target mass moves with original velocity
📖 Step-by-Step Solution & Conceptual Rationale:
For elastic collision of identical masses in 1D, velocities are completely exchanged upon impact (v1' = 0, v2' = v1).

MEDIUM • Physics (Secondary & College Level)
Surface tension of a liquid decreases when:
A
Pressure is reduced
B
Temperature is decreased
C
Impurity is added
D
Temperature is increased
✓ Correct Answer: D - Temperature is increased
📖 Step-by-Step Solution & Conceptual Rationale:
As temperature increases, molecular thermal kinetic energy increases, weakening intermolecular cohesive forces and decreasing surface tension.
