Which option lists the types of electromagnetic waves in order of increasing wavelength? 567170
visible light, ultraviolet, infrared
infrared, ultraviolet, visible light
visible light, infrared, ultraviolet
ultraviolet, visible light, infrared

The correct answer is ultraviolet, visible light, infrared.

Explanation:

Ultraviolet, visible light and infrared, all are known as electromagnetic waves because they have some magnetic as well as electrical components associated with them.

The wavelength of ultraviolet waves is in the range 10nm - 400nm.

The wavelength of visible light is in the range 380nm - 740 nm.

The wavelength of infrared waves is in the range 700nm - 1mm.

Hence, the order of increasing wavelength of the electromagnetic waves:

The question is incomplete, here is the complete question:

A solution is made by mixing 103. g of acetone and 137. g of acetic acid. Calculate the mole fraction of acetic acid in this solution. Round your answer to 3 significant digits.

The mole fraction of acetone in the solution is 0.438

Explanation:

To calculate the number of moles, we use the equation:

     .....(1)

Given mass of acetic acid = 137. g

Molar mass of acetic acid = 60 g/mol

Putting values in equation 1, we get:

Given mass of acetone = 103. g

Molar mass of acetone = 58 g/mol

Putting values in equation 1, we get:

To calculate the mole fraction, we use the equation:

Calculating the mole fraction of acetone:

Hence, the mole fraction of acetone in the solution is 0.438
