Question

a microwave oven had a 6 GHz source. of the energy incident on the inside of the door is 299mW/cm2 and the door has a 32x32 mesh screeb, what is the energy level passing through this screeb

Answer 1

326 32 & Mesh Screen at door energy incident on door = 299 mw 1 cm2 , Mopwoven oven source 6GHz Energy level passing thewigh screen is given by 0 Purpose of Screen Mesh as the door screen is designed light to pass thao ugh, allowing inside but the scree is also the longer dangerous ware length to allove visible you to see designed to stop and bounce them back into the chamber.. Now , E = wo. no plank's constant. & frequency E = 6.63610-34 X 6X 109 = 39.78 x 10- 25 To. Area of screen = 32x32 = 1024 cm². Total energy incident in = 1024 x 299 x 10-3 we - 306.176 W.
