476 nm = 4.76x10^[?] cm

4.76×10¯⁵ cm

Explanation:

We'll begin by converting 476 nm to m. This can be obtained as follow:

1 nm = 1×10¯⁹ m

Therefore,

476 nm = 476 nm × 1×10¯⁹ m / 1 nm

476 nm = 4.76×10¯⁷ m

Finally, we shall convert 4.76×10¯⁷ m to cm. This can be obtained as follow:

1 m = 100 cm

Therefore,

4.76×10¯⁷ m = 4.76×10¯⁷ m × 100 cm / 1 m

4.76×10¯⁷ m = 4.76×10¯⁵ cm

Thus,

476 nm = 4.76×10¯⁵ cm
