- Virtual and magnified
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A concave lens is diverging, meaning it spreads parallel rays outward.
It never forms real images because the rays diverge after passing through.
The image appears on the same side as the object (virtual).
The image is upright (erect) and smaller than the object (diminished).
Applications: spectacles for myopia, peepholes in doors, and some optical instruments.

- Torque is measured in candela
- Torque and candela are unrelated physical quantities.
- Torque is directly proportional to candela.
- Torque is inversely proportional to candela.
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Torque and candela measure completely different physical quantities.
Torque (τ) is the rotational equivalent of force: τ = Force × Lever arm.
Its SI unit is Newton-meter (N·m).
Candela (cd) is the SI unit of luminous intensity (brightness of light).

آواز کی لہریں ______ تابکاری ہیں۔
- Longitudinal
- Electromagnetic
- Latitudinal
- None of these
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Sound waves require a medium (air, water, or solid) to travel, so they are mechanical waves.
The particles of the medium vibrate parallel to the direction of wave propagation.
This makes sound waves longitudinal waves.
In a longitudinal wave, compressions and rarefactions carry the sound energy.
Therefore, sound waves are mechanical longitudinal waves and cannot travel in a vacuum.
