Question

how many hertz are in a uv light with a frequency of 2.3 x 10^9 mhz? give your answer in proper scientific notation. ? x 10^? hz enter the coefficient in the green box and the exponent in the yellow box. coefficient (green) exponent (yellow) submit

Explanation:

Step1: Recall the conversion factor

$1\ MHz = 10^{6}\ Hz$

Step2: Convert the given frequency

We have a frequency of $2.3\times 10^{9}\ MHz$. To convert it to Hz, we multiply by the conversion factor: $(2.3\times 10^{9})\times(10^{6})\ Hz$.
Using the rule of exponents $a^{m}\times a^{n}=a^{m + n}$, we get $2.3\times10^{9 + 6}\ Hz=2.3\times 10^{15}\ Hz$.

Answer:

Coefficient (green): 2.3
Exponent (yellow): 15
