What is the unit of electric current?
Ampere (A)
What is the formula for Einstein’s mass-energy equivalence?
E = mc^2
Name the 3 primary colours that make up light

State the second law of thermodynamics
Entropy of an isolated system never decreases; it either increases or remains constant
What is a solenoid?
A coil of wire designed to produce a magnetic field when an electric current passes through it
What does the photo-electric effect demonstrate about light?
Light can eject electrons from a metal surface, proving it has particle-like properties
Describe the double-slit experiment and its significance
It demonstrated the wave-like nature of light through interference patterns created by passing light through two slits
