For this case we must find a reasonable estimate, in scientific notation, for a wavelength given by:

0.000000492 meters

If we roll the decimal seven spaces to the right we have:

[tex]4.92 * 10 ^ {- 7}\ m[/tex]

The exponent is negative.

The expression can be written as:

[tex]5 * 10 ^ {- 7}\ m[/tex]

Answer:

Option C
