Answer:
least distance= 13mm
ratio of the lattice = 1 : 0.71 : 0.58
Explanation:
given λ₁ = 650nm = 650×10⁻⁹m,  λ₂ = 500nm = 500×10⁻⁹m
 
        
             
        
        
        
A) The temperature will increase.
Kinetic energy is the intrinsic energy carried by an object in motion. 
Explanation:
Increasing the kinetic energy of the molecules means that molecules rapidly. This causes an increased rate of collision between the molecules and between the molecules and the walls of the container. Most of these collisions are inelastic meaning that some of the energy in the collisions is lost as heat energy to the environment. This means the system becomes hotter.
