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.
Answer
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
According to the rule aᵐ×aⁿ=aᵐ⁺ⁿ, 4.83×10²×10⁻⁹ m=4.83×10²⁺⁽⁻⁹⁾ m = 4.83×10⁻⁷ m
Answer:
4.83, - 7
