Question

The wavelength of x rays are between 1 and 10 nanometers if a nanometer is equal to a billionth of a meter express the greatest wavelength of an x ray in meters write the expression using a negative exponer

Answer 1

Explanation:

The wavelength of x rays are between 1 and 10 nanometers.

1 nm = 10⁻⁹ m

The greatest wavelength is 10 nm.

10 nm = 10 × 10⁻⁹ m

= 10⁻⁸ m

Here, (-8) is the exponent of 10.

Hence, the wavelength of the greatest wavelength of x-ray is 10⁻⁸ m.
