Question

Red light emitted from neon lamp is found to be 780 nm convert it angstrom unit.?​

Answer 1

Answer:

78 angstrom

Explanation:

1nm - 10^(-9) m

1angstrom - 10^(-10) m

therfore 10nm = 1 angstorm

780 nm = 780 * 10 = 7800 angstorm

Answer 2

Answer:

7800 Å(Angstrom)

Explanation:

Nanometer($nm$) and Angstrom(Å) unit are  units of length in the metric system.

Nanometer($nm$) and Angstrom(Å) unit are related as

                                 $1nm = 10Å$

Wavelength of red light emitted from neon lamp $=$ 780nm

Since                        $1nm = 10Å$

Therefore                 $780nm= 780*10Å$ $=7800Å$
