Monochromatic blue light of wavelength 450 nm is shined on a slit of width LaTeX: aa. A diffraction pattern is observed on a screen 10 m away. What must LaTeX: aa be such that the width of the central diffraction maximum is 100 times the width of the slit

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.

Iknow the first part it is the average star i am not 100% sure

The disturbance in a transverse wave is perpendicular to the wave motion.unlike a transverse wave, the disturbance in a longitudinal wave is parallel to the wave motion (a), that is, back and forth.

The waves slow downn
