Question

The length of the shortest wavelength of visible light is about 0.00000039. What is the length in scientific notation

Answer 1

Given:

The given number is 0.00000039.

Required:

We need to find the scientific notation.

Step-by-step explanation:

Recall that a number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.

Consider the given number.

0.00000039

Multiply and divide this number by 10000000.

`0.00000039=0.00000039*(10000000)/(10000000)`
`0.00000039=3.9*(1)/(10000000)`
`0.00000039=3.9*(1)/(10^7)`
`0.00000039=3.9*10^(-7)`

Final answer:

`0.00000039=3.9*10^(-7)`
