The intensity of an electromagnetic wave is given by the following equation:
I = (ε0c/2)E02, where ε0 is the permittivity of free space, c is the speed of light in a vacuum, and E0 is the maximum amplitude of the electric field.
I added a related link below that shows how to derive this.

How are the different types of electromagnetic wave organized?
By frequency on the electromagnetic spectrum
What is the amplitude of a sound wave a measure of?
The amplitude of a sound wave is the measure of the intensity of the sound, such as loudness.
What happens when you increase electromagnetic wave?
To increase the intensity, if that's what you mean, more energy is required. That would also mean that the electromagnetic wave carries more energy.
How could you prove experimentally that energy is associated with wave?
Measure the motion of matter created by the mechanical wave, or measure the temperature change of matter created by the electromagnetic wave.
What part of the electromagnetic spectrum does the ultrasonic wave falls into?
An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.An ultrasonic wave is not an electromagnetic wave; it is a sound wave.
Is there a scale used to measure the intensity of a heat wave?
is there a scale used to measure the intensity of heat wave
The measure of a waves intensity?
The measure of the intensity of a wave is referred to as its amplitude.

As the intensity of an electromagnetic wave increases what happens to its frequency?

What gamma waves have?
Gamma waves have the shortest wavelength of any electromagnetic wave in the EM spectrum, the shortest wavelength means highest cyclic frequency, and highest intensity of any EM wave. (energy transferance by gamma waves is the strongest) *intensity is a measure of the height of the sine wave as opposed to to length, essentially more energy in a smaller crossectional area.
How could you prove experimentally that energy is associated with wave?
Measure the motion of matter created by the mechanical wave, or measure the temperature change of matter created by the electromagnetic wave.

Which wave is not electromagnetic wave?
Mexican Wave? A non-electromagnetic wave.
How the term intensity decibel and amplitude are related?
They are all measueres of sound waves. Amplitude is the term for the maximum difference in pressures between the peaks and troughs of a sound wave. Intensity is a measure of the energy content of a wave, and is proportional to amplitude squared. The decibel is an anthropic (based on human senses) measure of sound intensity, proportional to the logarithm of intensity.
What is the scientific definition for intensity?
Intensity is proportional to the square of the amplitude of vibration in case of mechanical wave such as sound waves But in case of light which is electromagnetic in nature, the intensity is the number of photons crossing unit area in one second
