The _______ of a wave is a measure of the amount of energy it carries

Answers

The word that best fits is frequency. The sentence is The frequency of a wave is a measure of the amount of energy it carries. There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h * frequency. So, the answer is frequency. Although you should know that wavelength is related to frequency and so it is also a measure of the amount of energy and it should also be other valid answer.

The word that best fits is frequency. Thus,the sentence is,the frequency of a wave is a measure of the amount of energy it carries.

The electromagnetic radiation consists of waves made up of electromagnetic field which are capable of propogating through space and carry the radiant electromagnetic energy.

The radiation are composed of electromagnetic waves which are synchronized oscillations of electric and magnetic fields . They are created due to change which is periodic in electric as well as magnetic fields.

There is a direct relationship between frequency and energy of a wave. The constant of proportionality is h, Planck's constant. So, Energy = h frequency. So, the answer is frequency.

A balloon with a volume of 1.50 L is compressed to a volume of 0.50 L (at a constant temperature).a. Do you expect the pressure of the gas in the balloon to increase or decrease? Why?

Answers

The pressure of the gas in the balloon is expected to decrease.

WHAT IS BOYLE'S LAW?

Boyle's law states that the volume of a given gas is inversely proportional to the pressure of the gas provided the temperature is constant.

Boyle's law is denoted by the equation: K = P/V.

This means that as the volume of the gas increases, the pressure decreases and vice versa.

Therefore, the pressure of the gas in the balloon is expected to decrease.

Answer : The pressure of gas in the balloon will be increases.

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto (1)/(V)$

From this we conclude that, as the volume of gas increases then the pressure of the gas will be decreases and as the volume of gas decreases then the pressure of the gas will be increases.

As per question, the volume of balloon decreases from 1.50 L to 0.50 L at constant temperature. So, the pressure of gas in the balloon will be increases.

Hnece, the pressure of gas in the balloon will be increases.
