Answer 1

begin math size 12px style Here comma space Time space Period comma space straight T space equals space 2 space ms space equals space 2 space cross times space 10 to the power of negative 3 end exponent space straight s Velocity comma space straight v space equals space 1250 space straight m divided by straight s straight v space equals straight lambda over straight T 1250 space equals space fraction numerator straight lambda over denominator space 2 space cross times space 10 to the power of negative 3 end exponent end fraction therefore straight lambda space equals space 2.5 space straight m end style
