Why are objects Coloured? Objects appear different colours because they absorb some colours (wavelengths) and reflected or transmit other colours. The colours we see are the wavelengths that are reflected or transmitted. White objects appear white because they reflect all colours. Black objects absorb all colours so no light is reflected. Why is red the […]

What is the force on a current carrying conductor? The force on a current-carrying wire in a magnetic field is F = IlB sin θ. Its direction is given by RHR-1. What is the force on a current carrying wire that is parallel? Force on a current-carrying wire that is parallel to the magnetic field […]
