Some cameras used in scientific research can take one picture every 0.00000278 seconds. Write this number in scientific notation.

The number 0.00000278 can be written in scientific notation by moving the decimal point to the right until there is only one non-zero digit to the left of the decimal point. The number of places the decimal point is moved becomes the negative exponent of 10.

Starting with 0.00000278, we move the decimal point 6 places to the right:

\[
0.00000278 = 2.78 \times 10^{-6}
\]

So, the number 0.00000278 in scientific notation is:

\[
2.78 \times 10^{-6}
\]
