Question

a blue light has a wavelength of 483 nm. what is the wavelength in meters? give your answer in proper scientific notation. ?×10^? m enter the coefficient in the green box and the exponent in the yellow box. coefficient (green) exponent (yellow)

Explanation:

Step1: Recall the conversion factor

1 nm = 1×10⁻⁹ m

Step2: Convert 483 nm to m

483 nm = 483×1×10⁻⁹ m = 4.83×10²×10⁻⁹ m

Step3: Use the exponent - rule

aᵐ×aⁿ=aᵐ⁺ⁿ, so 4.83×10²×10⁻⁹ m = 4.83×10²⁺⁽⁻⁹⁾ m = 4.83×10⁻⁷ m

Answer:

Coefficient (green): 4.83
Exponent (yellow): - 7
