Question

This question is purely for 11th std science students.

Explain this paragraph in a simple and an understandable way: "In order to determine the position of an electron, we must use a meterstick calibrated in units of smaller than the dimensions of an electron ( electron is a point sized object and is therefore, dimensionless ) To observe an electron, we can illuminate it with light, or electromagnetic radiation. The light used must have a wavelength smaller than the dimensions of an electron"

Answer 1

Explanation:

Just like we use a calibrated tool to measure, even atoms can be measured with photons of light.
