Q(3): Answer bv (True or False) 1. X-ray have very short wavelengths than the light wavelengths and as a result, its energy is much lower than that of visible light. 2. Ionic solids easily dissociated into its ions in molten state and show high electrical conductivity. while ionic solids are anisotropic and brittle linked with very strong force of interactions. 3. Most Bravais lattices are of the type of primitive unit cell. 4. The axial relationship of a rhombohedral crystal system is given as (a = b = c). 5. There are two rotational operation symmetry of equilateral traingle? 6. The d-spacing of various plane provides information about the structure of the crystal. 7. The force of attraction between atoms or ions is minimum at equilibrium distance (r = r.). 8. X-ray have a very short positive wavelength that lies in the range of 1 angstrom.

If you are shining light on a Pt electrode and no electrons are emitted, what do you have to do to generate electrons? Decrease the wavelength of the light to increase the energy of the photons to emit electrons Electrons can not be emitted from Pt because like any other noble metal it does not react, even under light exposure (unlike other metals, e.g. Na, Sr or Cu) Increase the wavelength of the light to increase the energy of the photons to emit electrons Wait longer times or increase the intensity of the light source, since the energy of the absorbed light is not high enough to emit electrons from Pt surface
