Light Quizzes & Trivia

If you’re reading this right now, you can thank light. Light is the very special part of the electromagnetic spectrum that’s visible to the eye – all the colors of the rainbow from red to violet. Besides its role in illuminating world, light plays an important role in physics, where we can define and quantify everything about light, from its wavelength to its frequency to its role in a vacuum.

Think you can explain the difference between reflection and refraction? Want to bet that you can correctly calculate the energy of light based on its frequency? Whether you’re a quantum physicist on the make or you still think light travels through a special magical ether to get to its destination, take our quiz to learn all there is to know about light!
