(a)
The wavelength with maximum intensity emitted from bulb and then compare it with the wavelength with maximum intensity emitted by sun.
(b)
Whether the light emitted by bulb will be same, redder or bluer than sun. Explain the answer. Using this answer, explain why professional photographer uses different light for indoor outdoor.
(c)
To explain:
Whether all the energy emitted by incandescent bulb is in visible range or not. Using this answer explain why the incandescent bulbs are usually so hot.
(d)
To explain:
Why fluorescent bulbs emits more visible light than incandescent bulbs.
(e)
Whether the fluorescent light bulbs are cost effective or not. What factors, other than initial cost and energy efficiency, need to be considered to know it.

- Show that the units 1 v2/Q = 1 W, as implied by the equation P = V²/R. Starting with the equation P = V²/R, we can get an expression for a watt in terms of voltage and resistance. The units for voltage, V, are equivalent to [? v2 v2 A, are equivalent to J/C ✓ X . Therefore, 1 = 1 = 1 A V1 J/s Ω V-A X = 1 W. . The units for resistance, Q, are equivalent to ?
