Answer 1.a) Classical physics fails in explaining blackbody radiation but explains the internal energy's variation with T.
This is wrong because according to classical physics, there should be no limit to the energy of the light produced by the electrons vibrating at high frequencies. But experimentally, the blackbody spectrum always becomes small at the left-hand side (short wavelength, high frequency). That is variation of internal energy with temperature is not explained by classical physics .
3.The mean free path of free electrons in a metal at room temperature is approximately (b) 10 nm.
4. As we know larger is the refractive index smaller is the speed of light in that medium .
1.Which of the following is incorrect? (a) Classical physics fails in explaining blackbody radiation but explains...
1. Fill out the following table by indicating which general technique (light microscopy (LM) or electron microscopy (EM]) could be used to observe each structure or phenomenon. Put "no" in the box if the technique could not be used. If light microscopy can be used, name one technique (bright-field, phase-contrast, fluorescence, etc.) that you think would be effective. You will find some useful information in Appendix 1 of this manual and Chapter 18 of your textbook. Structure or phenomenon Could...
