Two slits are 0.135 mm apart. A mixture of red light (λ= 645 nm) and blue light (λ= 445 nvm) falls on two slits. If an interference pattern is produced on a screen 2.8 m away, find the distance between the 1st red fringe and the 1st blue- violet fringe.

Velocity is a description of both speed and direction, therefore it - a vector - a force arrow - the same as acceleration - a magnitude

Which of the following statements comparing electron microscopy and light microscopy is false? which of the following statements comparing electron microscopy and light microscopy is false? both the electron microscope and the light microscope use the same wavelengths for illumination. images produced by light microscopes can be in color, whereas electron microscope images are black and white unless they are artificially colored. the electron microscope has greater resolution than the light microscope. electron microscopes can allow examination of viruses and internal cell structures, whereas light microscopes are limited to objects that are 0.5 micrometers and larger. request answer
