The nature of light is quite interesting because it has two sides:

1. Wave Properties:

   • Light can act like a wave. This means it can do things like interfere with other waves and bend around corners, which is called diffraction.
   • The wavelength, which is how long the waves are, is measured in nanometers (nm). In the range we can see, it goes from about 400 nm for violet light to 700 nm for red light.

2. Particle Properties:

   • Light can also act like tiny particles called photons.
   • Each photon has energy, and we can figure that out using the formula: energy (E) equals a number (h) multiplied by frequency (f). The number h is very small, about 6.626 times 10 to the power of -34.

This combination of wave and particle behaviors shows how complex and important light is in physics.
