A plane wave with a wavelength of 500 nm is incident normally ona single slit with a width of 5.0 x 10^-6 m. Consider waves that reach a point on a far-away screen such thatrays from the slit make an angle of 1.0° with the normal. The difference in phase for waves from the top and bottom of the slit is .

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Give your knowledge of these things in your paper, you will compare and contrast analog and digital signals to determine which is more reliable for encoding and transmitting information. you’ll compare these features: signal shape numerical values for signal measurements amount of data that can be transmitted energy requirements privacy and security (ability of the signal to be encoded in a secret code) clarity of signal in the space provided, write down what you already know about any of these features. if you’re not sure, write down questions you might have about the features.
