4.76 × 10¯⁵ cm

Explanation:

The conversion of 476 nm to cm can be obtained as follow:

1. Conversion of 476 nm to m

Recall

1 nm = 1 × 10¯⁹ m

Therefore,

476 nm = 476 × 1 × 10¯⁹ = 476 × 10¯⁹ m

2. Conversion of 476 × 10¯⁹ m to cm

Recall:

1 m = 100 cm

Therefore,

476 × 10¯⁹ m = 476 × 10¯⁹ × 100

476 × 10¯⁹ m = 476 × 10¯⁷ cm

476 × 10¯⁹ m = 4.76 × 10¯⁵ cm

Therefore,

476 nm is equivalent to the 4.76 × 10¯⁵ cm
