Question

An astronomers infrared telescope is able to detect radiation with a wavelength of 2.68 x 10^-6 meters. Write this number in standard notation

Answer 1

To convert to standard notation, since the exponent of 10 is negative, we need to add zeros to the start of the number. In this case, 6 zeros and the first one is the integer zero:

`2.68x10^(-6)=0.00000268`
