Physics Medium

Which type of wave requires no medium and can travel through a vacuum at the speed of light?

  • ASound wave
  • BElectromagnetic wave
  • CWater wave
  • DSeismic wave
Permalink
Correct Answer: Option B — Electromagnetic wave

Physics Medium

Which kinetic theory explains that gas pressure results from molecular collisions with container walls?

  • ABoyle's Law
  • BAvogadro's Law
  • CCharles's Law
  • DKinetic molecular theory
Permalink
Correct Answer: Option D — Kinetic molecular theory
Explanation: The kinetic molecular theory explains that gas pressure results from the constant random motion and elastic collisions of gas molecules with the walls of their container.

Physics Hard

What is the unit of measurement for radioactive activity equal to one nuclear disintegration per second?

  • AGray
  • BBecquerel
  • CSievert
  • DRem
Permalink
Correct Answer: Option B — Becquerel
Explanation: The Becquerel is the SI unit of radioactivity named after Henri Becquerel defined as one nuclear disintegration per second and replaced the older unit Curie in the SI system.

Physics Medium

Which scientist discovered electromagnetic induction demonstrating that a changing magnetic field induces current?

  • AMichael Faraday
  • BJames Clerk Maxwell
  • CNikola Tesla
  • DHeinrich Hertz
Permalink
Correct Answer: Option A — Michael Faraday
Explanation: Michael Faraday discovered electromagnetic induction in 1831 demonstrating that a changing magnetic flux through a conductor induces an electromotive force forming the basis of generators.

Physics Medium

Which principle states that pressure in a static fluid increases with depth depending on fluid density?

  • ABernoulli's Principle
  • BArchimedes' Principle
  • CPascal's Principle
  • DHydrostatic pressure principle
Permalink
Correct Answer: Option D — Hydrostatic pressure principle
Explanation: The hydrostatic pressure principle states that pressure in a static fluid increases linearly with depth depending on fluid density and gravitational acceleration expressed as P equals rho g h.

Physics Easy

Which property of a wave is the distance measured from one crest to the next crest?

  • AAmplitude
  • BFrequency
  • CWavelength
  • DSpeed
Permalink
Correct Answer: Option C — Wavelength
Explanation: Wavelength is the distance between two successive identical points on a wave such as crest to crest and is inversely related to frequency for waves travelling at the same speed.

Physics Hard

Which force holds quarks together inside protons and neutrons at subatomic distances?

  • AWeak nuclear force
  • BStrong nuclear force
  • CGravitational force
  • DElectromagnetic force
Permalink
Correct Answer: Option B — Strong nuclear force
Explanation: The strong nuclear force mediated by gluons holds quarks together inside protons and neutrons and is the strongest of the four fundamental forces operating only at subatomic distances.

Physics Hard

What is the phenomenon where a material loses all electrical resistance below a critical temperature?

  • ASemiconduction
  • BFerromagnetism
  • CParamagnetism
  • DSuperconductivity
Permalink
Correct Answer: Option D — Superconductivity
Explanation: Superconductivity is the phenomenon where certain materials exhibit zero electrical resistance below a critical temperature allowing current to flow indefinitely without energy loss.

Physics Medium

Which phenomenon allows optical fibres to transmit light signals over long distances?

  • ATotal internal reflection
  • BRefraction
  • CDiffraction
  • DDispersion
Permalink
Correct Answer: Option A — Total internal reflection
Explanation: Total internal reflection occurs when light travelling in a dense medium hits the boundary at an angle greater than the critical angle causing all light to reflect back inside the fibre.

Physics Hard

Which law states that energy radiated by a black body is proportional to the fourth power of its temperature?

  • AStefan-Boltzmann Law
  • BBoltzmann's Law
  • CWien's Law
  • DNewton's Cooling Law
Permalink
Correct Answer: Option A — Stefan-Boltzmann Law
Explanation: The Stefan-Boltzmann Law states that total energy radiated per unit area of a black body is proportional to the fourth power of its absolute temperature expressed as P equals sigma T to the power 4.
