What is the speed of an electromagnetic wave that has a wavelength of 8.6 x 10-5 m?

The speed of the given electromagnetic wave is  3 x 10⁸ m/s.

Explanation:

Electromagnetic wave is a type of energy that is commonly known as light energy. The speed of light in air is about 3 x 10⁸ meters per second (m/s).

All electromagnetic waves travel at the same speed which is equal to speed of light, approximately  3 x 10⁸ meters per second (m/s) through a vacuum or air.

Therefore, the speed of the given electromagnetic wave is  3 x 10⁸ m/s.

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
