an orange light has a wavelength of 630 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 630 nm to m
630 nm=630×1×10⁻⁹ m = 6.3×10²×10⁻⁹ m
Step3: Use the exponent - rule
According to the rule aᵐ×aⁿ=aᵐ⁺ⁿ, 6.3×10²×10⁻⁹ m = 6.3×10²⁺⁽⁻⁹⁾ m=6.3×10⁻⁷ m
Answer:
Coefficient (green): 6.3 Exponent (yellow): - 7
