1.	The wavelength of a light is of the order of `6400 Å`. Express this in micron and metre.A. `0.64` micronB. 0.84 micronC. 0. 24 micronD. 0. 34 micron
Answer» Correct Answer - A As, `1 Å=10^(-10)` `:.` Wavelength of light `=6400 Å=6400xx10^(-10)m=6.4xx10^(-7)m` Also 1 micron`=10^(-6)`metre Wavelength of light (in micron) `=(6.4xx10^(-7))/(10^(-6))`micron `=0.64` micron
