Planck constant

Did you know light and energy are linked by a tiny constant?

Imagine you're trying to figure out how much energy a tiny particle of light carries. Without knowing a specific constant, it's like trying to cook with an unknown ingredient.

Think of Planck's constant as a secret recipe ingredient that tells us how much energy light particles have based on their color (frequency). This secret ingredient helps us understand the energy of light at a tiny scale.

Example

A photon with a frequency of 500 THz (terahertz) has an energy of 4.14 x 10⁻¹9 Joules (J), using Planck's constant (h = 6.62607015 x 10^-34 J⋅Hz⁻¹).

Remember this

Planck's constant (h) is the secret ingredient that links light's color (frequency) to its energy, helping us unlock the mysteries of light at the smallest scales.
