An electron microscope uses magnets to accelerate electrons with negligible initial speed through apotential difference of 50 million volts. Calculate the ratio of the resolution of this electron microscope to theresolution of a microscope that uses visible light with a wavelength of 5.00 × 10−7 m through a circularaperture with an aperture of 5.00 mm.
How many photons are emitted during a 2.50-second burst of light from a 445 nm laser that operates at 0.400 watts?
An electron microscope produces electrons with a 2.00-pm wavelength. If these are passed through a 1.00-nm single slit, at what angle will the first diffraction minimum be found?
