Question

The wavelength of a certain type of light is 0.0000014 inches. Write the wavelength in scientific notation.

Answer 1

Answer:
`1.4* 10^(-6)`

Explanation:

Given

The wavelength of light is 0.0000014 inches

Here, seven digits are followed by a decimal point

To convert it to scientific notation, convert it into a fraction i.e.

`=0.0000014=(14)/(10,000,000)`

In the denominator, there are 7 zeroes

`\therefore 0.0000014=(14)/(10^7)\\\\\Rightarrow 0.0000014=14* 10^(-7)\\\\\Rightarrow 0.0000014=1.4* 10^(-6)`
