How Do Photons Create Different Colors of Light?

[gaurav pant]

i have read that light is made up of photons :rofl: how does similar photons can produce lights of different colours(pardon me if this appears a silly question to u

The color of a photon depends on its wavelength $\lambda$ or frequency $f$ or energy $E$ (take your pick). They're all related to each other:

$$c = \lambda f$$

$$E = hf$$

$$E = hc / \lambda$$

where $c$ is the speed of light and $h$ is Planck's constant.

It is not a silly question at all! In fact, it is a very interesting and important question in the field of physics. The color of light is determined by the energy or wavelength of the photons that make it up. Each color of light corresponds to a different wavelength or energy level. So, while all photons are similar in their basic properties, they can have different energies and wavelengths, resulting in different colors of light. This is similar to how different musical notes can be produced by the same instrument, but at different frequencies. So, even though all light is made up of photons, the specific arrangement and energy levels of these photons can result in a wide range of colors.
