Final answer:
The wavelength of visible blue light, 0.0000475 centimeters, in scientific notation is 4.75 × 10⁻⁵ centimeters.
Step-by-step explanation:
The measurement of the wavelength of visible blue light given is 0.0000475 centimeters. To write this in scientific notation, we need to move the decimal point in the number to the right to find the equivalent number that is between 1 and 10. After moving the decimal point 5 places to the right, the number becomes 4.75. We then multiply 4.75 by 10 to the power of negative 5, because we moved the decimal point 5 places. Hence, the scientific notation of 0.0000475 centimeters is 4.75 × 10⁻⁵ centimeters.
