Interpretation Introduction

Interpretation:

The curve which tells about two consequences of great biological significance on earth and astronomers who are able to determine the temperature at the surface of stars should be explained.

Concept Introduction:

Black Body Radiation

When solids are heated, they emit radiations which vary over a broad range of wavelengths. For example: when solid is heated, the color is changed which is continued with a further increase in temperature. When the temperature increases, this change in colour occurs from a lower frequency to a higher frequency region. For example, in many cases, it changes from red to blue. An ideal body which can emit and absorb radiation of all frequencies is called a black body. The radiation emitted by such bodies is called black body radiation. The examples of blackbody radiation are red glow of the element of an electric stove and the bright white light of a tungsten light bulb.

Figure.1

Thus, the variation of frequency for a black body radiation depends on the temperature. At a given temperature, the intensity of radiation is increased with an increase in the wavelength of radiation which increases to a maximum value and then decreases with an increase in the wavelength. This phenomenon couldn’t be explained with Maxwell’s suggestions. Hence Planck proposed the Planck’s quantum theory to explain this phenomenon.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule
