(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.

- Page 2 SECTION A Answer ALL questions in Section A [Expect to use one single-sided A4 page for each Section-A sub question.] Question A1 SPA6308 (2024) Consider Minkowski spacetime in Cartesian coordinates th = (t, x, y, z), such that ds² = dt² + dx² + dy² + dz². (a) Consider the vector with components V" = (1,-1,0,0). Determine V and V. V. (b) Consider now the coordinate system x' (u, v, y, z) such that u =t-x, v=t+x. [2 marks] Write down the line element, the metric, the Christoffel symbols and the Riemann curvature tensor in the new coordinates. [See the Appendix of this document.] [5 marks] (c) Determine V", that is, write the object in question A1.a in the coordinate system x'. Verify explicitly that V. V is invariant under the coordinate transformation. Question A2 [5 marks] Suppose that A, is a covector field, and consider the object Fv=AAμ. (a) Show explicitly that F is a tensor, that is, show that it transforms appropriately under a coordinate transformation.
