What is the correct single pole light switch wiring diagram for installing a new light switch in a residential setting?

To install a single pole light switch in a residential setting, connect the black wire from the power source to the brass screw terminal on the switch, and connect the black wire from the light fixture to the other brass screw terminal. Connect the white wires together with a wire nut, and connect the ground wire to the green screw terminal on the switch. Make sure to turn off the power before starting the installation.
