Halogen light-bulbs allow their filaments to operate at a higher temperature than the filaments in standard incandescent bulbs. For comparison, the filament in a standard light-bulb operates at about 2900 K, whereas the filament in a halogen bulb may operate at 3400 K.

(a) Which bulb has the higher peak frequency?

(b) Calculate the ratio of peak frequencies (ƒhal > ƒstd).

(c) The human eye is most sensitive to a frequency around 5.5 × 1014 Hz. Which bulb produces a peak frequency closer to this value?
