To write \(0.047\) in scientific notation, we need to express the number as \(a \times 10^n\), where \(1 \leq a < 10\) and \(n\) is an integer.

1. Move the decimal point two places to the right to make \(0.047\) into \(4.7\), which gives us the number \(4.7\).
2. Since we moved the decimal two places to the right, we must multiply by \(10^{-2}\) to account for this shift.

Thus, \(0.047\) in scientific notation is:
\[
4.7 \times 10^{-2}
\]

Therefore, the correct option is **\(4.7 \times 10^{-2}\)**.
