This energy is known to be quantised, existing in light packets called photons.[/cs_text][cs_text]
[/cs_text][cs_text]According to Planck’s formula, absorbed or emitted energy is inversely proportional to wavelength. Therefore, electrons can only emit or absorb specific wavelengths.[/cs_text][/cs_column][/cs_row][/cs_section][/cs_content]
