Answer 1

@KL-RC

Answer 2

@abb0t

Answer 3

its okay @KL-RC , can u tag someone who might know this

Answer 4

\[\dfrac{1}{\lambda} = R\left(\dfrac{1}{n_f^2} - \dfrac{1}{n_i^2}\right)\]

Answer 5

Thnx @ParthKohli ...then ithink it should be 5/R

Answer 6

\[\dfrac{1}{\lambda} = R\left(\dfrac{1}{4} - \dfrac{1}{25}\right)\]\[= R\cdot \dfrac{21}{100}\]Take the reciprocal of both sides...

Answer 7

yes..approx 5/R

Answer 8

OK, yes. I thought you calculated that in exact values and got a little worried.

lol
