Part A While using a dimmer switch to investigate a new type of incandescent light bulb, you notice that the light changes both its spectral characteristics and its brightness as the voltage is increased. If the wavelength of maximum intensity decreases from 1800 nm to 1620 nm as the bulb's voltage is increased, by how many °C does the filament temperature increase?
