Question

Number of waves of orange light emitted by krypton in 1 m is ____________.

Answer 1

Step 1: Given

The length is 1 meter (given).

As we know the wavelength of krypton ($Kr$) is$605nm.$

Step 2: Formulae

Since wave number $n=\frac{1}{\lambda }where\lambda iswavelength$

$$\begin{gathered} 1wave=605\times {10}^{-9}m \\ sofornumberofwavesin1m \\ \frac{1}{605\times {10}^{-9}}waves=1m \end{gathered}$$

The number of Waves =$1652892.562$.

Hence, The number of waves of orange light emitted by krypton in 1 m is$1652892.562$.
