- Difference of light
- Interference of light
- Polarization of light
- Reflection of light
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
- Brewster’s angle is the angle of incidence at which reflected light becomes completely polarized.
- At this angle, the reflected and refracted rays are perpendicular to each other.
- It’s given by:
tan(θₚ) = n₂/n₁,
where θₚ is Brewster’s angle.
- A comparison using “like” or “as”
- A story that teaches a lesson
- A figure of speech where one thing is said to be another
- An exaggeration of reality

Explanation
A metaphor directly compares two unlike things without using "like" or "as".
Example: "Time is a thief." — Time is not literally a thief, but it's being described as if it is one.
- At equilibrium (mid) position
- At half amplitude
- Always constant
- None of these

Explanation
In simple harmonic motion (SHM), the restoring force is given by:
F = -kx
Where:
- F is the restoring force
- k is the spring constant
- x is the displacement from the equilibrium position
The restoring force is minimum when displacement x = 0, i.e., at the equilibrium position.
- In same direction
- Opposite in direction
- Perpendicular to each other
- Independent of each other

Explanation
- In SHM, the restoring force always acts towards the equilibrium position, trying to bring the object back.
- Displacement is away from equilibrium, so they are in opposite directions.
- This relationship is given by F = -kx, where:
- F = restoring force
- x = displacement
- – sign shows they are in opposite directions.

Explanation
Definition:
Absolute zero is the temperature at which a system has the minimum possible energy and all thermal motion of particles ceases.
On the Celsius Scale:
This point corresponds to -273.15 degrees Celsius.
On the Kelvin Scale:
The Kelvin scale is an absolute scale where absolute zero is set as 0 K.
- Greater than 1
- Less than 1
- Equal than 1
- Cannot be predicted

Explanation
- When half of the reactants are converted to products, the concentration of products and reactants becomes equal at equilibrium.
- So, the numerator and denominator of the equilibrium expression are equal.
- Therefore, Kc = 1, which means the system is balanced between forward and reverse reactions.

Explanation
Kilowatt-hour is the unit of ENERGY.
Watt or Kilowatt is the unit of power.
Kilowatt-hour (KWh) is a unit of Electrical Energy.
We know that, Power×time=Energy
⇒ Kilo-Watt×Hour=Energy
1KWh is electrical energy consumed when an electrical equipment of power 1 KiloWatt is operated for 1 Hour.
- Temperature is constant
- Pressure is constant
- Volume is constant
- Both pressure and temperature vary
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Boyle's law holds when the temperature is constant and the amount of gas (number of moles) remains fixed in a closed system.
The law states that the pressure of a gas is inversely proportional to its volume under these conditions
Meaning that if the temperature and mass of the gas don't change
The product of pressure and volume will remain constant (PV = k)

Explanation
To find the energy stored in a capacitor, we use the formula:
E=1/2CV^2
Where:
Calculation:
E=1/2×4×10^−6×(100)^2
E=1/2×4×10^−6×10000
E=2×10^−6×10000
=0.02J
- Ampere
- Newton
- Farad
- None of these
