Question

You are an engineer designing a switch that works by the photoelectric effect. The metal you wish to use in your device requires $6.7 \times 10^{-19} \mathrm{J} /$ atom to remove an electron. Will the switch work if the light falling on the metal has a wavelength of 540 nm or greater? Why or why not?

Step 1

62 \times 10^{-34} \, \text{J} \cdot \text{s}\)), $c$ is the speed of light ($3 \times 10^8 \, \text{m/s}$), and $\lambda$ is the wavelength of the light (540 nm or $540 \times 10^{-9} \, \text{m}$). Plugging in the values, we get: \[E = \frac{(6.62 Show more…
