Question

What is Planck’s equation

Answer 1

Max Planck theorized that energy was transferred as a pocket known as quanta, equal to h.

The variable h is a constant equal to 6.63 × 10 ^-34 J·s

• This equation allows us to calculate the energy of photons, given their frequency.
• If the wavelength is given, the energy can be determined by first using the wave equation to find the frequency, then using Planck’s equation to calculate energy.
• The Planck's Equation:

E= h

E=

E- energy

h- 6.63 × 10 ^-34 Planck's equation Unit - J·s

c- 3 x 10⁸ Velocity of lightUnit - s

- Wavelength(will be given in problem) Unit - nm
