What does the slope of a positive linear line on a Maximum kinetic energy vs frequency graph represent

1 answer

The slope of a positive linear line on a Maximum kinetic energy vs frequency graph represents the value of Planck's constant (h). This is because the equation for the graph is given by the formula:

\( E_{max} = h \cdot f \)

where \( E_{max} \) represents the maximum kinetic energy of the ejected electrons, \( f \) represents the frequency of the incident light, and \( h \) represents Planck's constant.

Therefore, the slope of the line represents the value of Planck's constant, which is a fundamental constant in quantum mechanics.
