a blue light has a 460 nm wavelength. what is the wavelength of the light 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.
Answer
Explanation:
Step1: Recall the conversion factor
1 nm = 1×10⁻⁹ m.
Step2: Convert 460 nm to m
460 nm = 460×1×10⁻⁹ m = 4.6×10²×10⁻⁹ m.
Step3: Use the exponent - rule
According to the rule aᵐ×aⁿ=aᵐ⁺ⁿ, 4.6×10²×10⁻⁹ m = 4.6×10²⁺⁽⁻⁹⁾ m = 4.6×10⁻⁷ m.
Answer:
4.6; - 7
