Question

Your eye is most sensitive to green light with a wavelength of around 550 nm. What energy must an electron have to exhibit the same de Broglie wavelength?

Expert Solution

Step 1

de-Broglie wavelength ( $λ$ )

According to de-Broglie, a matter can show both particle character and wave character.

The equation to find energy is;

$\begin{array}{rcl} E & = & \frac{hc}{λ} \\ h & = & Planck' s constant = 6.626 \times 10^{- 34} Js \\ c & = & speed of light = 3 \times 10^{8} m / s \\ λ & = & wavelength \end{array}$
