well i found the answer before anybody answers me, i thought i should post it for future ref same book, page 440 explains in detail about how shorter wavelength can be greater affected by the environment than long wavelengths. As an example, the large ripples on a pond can travel along...

hmm...I think it would be sth like this: shorter wavelength -> higher energy particles -> more collision with dust cloud particles is that correct?

Hi all I was reading through an astrophysics book{1} and there I came across this sentence: " A dust cloud can either scatter or absorb light that passes through it. Since shorter wavelengths are affected more significantly than longer ones, a star lying behind the cloud appears reddened...

Thanks all, Is the driver`s condition (seated or unseated ) considered as the third input? I mean, the first input is right door, the second input is the left door, and the third input is the driver?

Hey all, How can I draw a diagram of some logic circuit that will light an LED if either or both the left and right door of a car are open and if the driver is seated ? Assume that the doors and seat are equipped with switches, and that only NAND gates are available. ( My circuit should...
