B) Show that Maxwell’s equations, when applied in a vacuum (i. e. no chargedensity or current density), give thewave equationsfor light:μ00∂2~E∂t2−∇2~E= 0;μ00∂2~B∂t2−∇2~B= 0(5)You need to show your work for full credit. Hint: take the curl of the righttwo equations in Eq. 1 and use the identity:∇×(∇×~F) =∇(∇·~F)−∇2~F(6)where∇2~Fis thevector Laplacian, whose components are the Laplacian ofthe individual components of~F. You will also need to use the fact that theordering of two derivatives can be interchanged.

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?
