A laser with wavelength is shining light on a double slit with slit separation 0.300 . This results in an interference pattern on a screen a distance away from the slits. We wish to shine a second laser, with a different wavelength, through the same slits. What is the wavelength of the second laser that would place its second maximum at the same location as the fourth minimum of the first laser, if = 0.300 ?
An artillery shell is fired with the initial velocity of 300 m/s at 54.7° above the horizontal. To clear an avalanche, it explodes on the mountainside 55.0 s after firing. What is the x and y components of the shell where it explodes, relative to its..
