Chapter 5, Problem 57EAP

(a)

To determine

The wavelength with maximum intensity emitted from bulb and then compare it with the wavelength with maximum intensity emitted by sun.

(b)

To determine

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 determine

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 determine

To explain:

Why fluorescent bulbs emits more visible light than incandescent bulbs.

(e)

To determine

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.

Let's assume that the brightness of a field-emission electron gun is given by β = 4iB π² d²α² a) Assuming a gun brightness of 5x108 A/(cm²sr), if we want to have an electron beam with a semi-convergence angle of 5 milliradian and a probe current of 1 nA, What will be the effective source size? (5 points) b) For the same electron gun, plot the dependence of the probe current on the parameter (dpa) for α = 2, 5, and 10 milliradian, respectively. Hint: use nm as the unit for the electron probe size and display the three plots on the same graph. (10 points)
