Ascientist uses a red light with a wavelength, 2 = 7 • 10 meters, to
determine the width of a slit (w). if the distance from the slit to the light
source is 1.1 meters and the distance from the center of the diffraction pattern
to the first nodal line is 2.5 cm, calculate the width of the slit (w).
(hint: xl = alw; i (red) = 7 . 10m, x = 2.5 cm, l = 1.1 meters)
a. 3.1 . 10^-7 meters
b. 7.7. 10^-7 meters
c. 3.1 . 10^-5 meters
d. 0.03 centimeters
e. 3.2 • 10^4 meters

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
