Answer #1

a) white colour means all the seven colour.. But our blood is absorb all this colour except red.. So we see blood appear RED..

b) According to the Rayleigh scattering the scattering of light is inverse proportional to the wave length of light in power four...wave length of violet and blue are smaller then other light.. So this light is more scattered... So we see the sky is blue..

Our eye is more effect blue light as compare to violet light... So our eye is see only blue light..

C) No,coronavirus is not seen in light microscop.. Because light microscop is measure 200nm... But the coronavirus is 80nm nearly.... So we can not seen corona virus in light microscop...

A diffraction grating is made with 750 lines per millimeter is illuminated with violet light of wave length 400nm. How many lines can be observed with this grating? If the intense white light is incident on the same diffracting grating what is the angular separation between the violet edge (400nm) and red edge (700nm)? What is the highest order in which the complete visible spectrum can be seen using this grating (λ =400-700nm)?

A current is detected in a photoelectric-effect experiment when the cathode is illuminated with green light. Part A Will a current necessarily be detected if the cathode is illuminated with blue light? Select the correct answer and explanation. (1)Photons of blue light have less energy than photons of green light. Therefore, if there is a current in a photoelectric-effect apparatus with green light, then there could be no current with blue light. (2)Photons of blue light have less energy than...
