An object is first seen in red light and then in violet light through a simplemicroscope.In which case is teh magnifying power of simple microscope greater?

For a given single slit,the diffraction pattern is obtained on a fixed screen,first by using red ligth and then with blue light.In which case,will the central maxima,in the observed diffraction pattern,have a larger angular width?

If red light and violet light rays are of focal length f_r adn f_v then which one of the following is true?

Out of red and blue lights, for which colour is the refractive index of glass greater?

Microscopes in which object is illuminated by ultraviolet light can give higher magnifications than the icroscopes that use visible light. how do you explain this?

An electron microscope uses electron accelerated by a voltage of 50kV. Determine the de-Broglie wavelengths associated with the electrons. If other factors (such as numerical aperture etc) are taken to be roughly the same how does the resolving power of electron microscope compare with that of an optical microscope which uses yellow light?

Which type of object allows light to pass through?

How does the power of a convex lens vary,if the incident violet light is replaced by red light?

Ultraviolet light is incident on two photosensitive materials, having work functions W_1 and W_2 , where W_1 > W_2 . In which case will the kinetic energy of emitted electrons be greater? Why?

Which of the violet and red lights will be deviated more by a prism and why?
