Question

find the ratio of energy of two radiation X and Y having wavelength 200 Angstrom &300 Angstrom
​

Answer 1

Answer:

$E_{2} = 1.5E_{1}$

Explanation:

lynda(1) = 200 Â            _ _ _(Â that means Angstrom)

lynda(2) = 300 Â

so,

$Energy_{1}$ = Hc / lynda(1)

$Energy_{2}$ = Hc / lynda(2)

the ratio of energy =

$E_{1} /E_{2} = lynda(2)/lynda(1)$          _  _ _ (E1 = E2 so, i can write)

put the value of lynda 1 and lynda 2

$E_{1} /E_{2} = 300/200\\E_{1} /E_{2} = 3/2$

so,

the ratio of energy of two radiation is = $E_{2} = 1.5E_{1}$
