There are two types of LEDs (Light Emitting Diodes) that can produce yellow light. One manufacturer offers an LED that emits only yellow light of wavelength 590 nm. Another manufacturer offers a unit that is actually two LEDs, one that emits red light with a wavelength of 630 nm, the other emits green light with a 540 nm wavelength. The yellow light from both LEDs looks identical when shined on a wall. Suppose that each type of LED was used to shine light through a diffraction grating. In each case, there will be a pattern that appears on the screen. Describe the differences (if any) between those patterns as completely as you can.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
