How does the amplitude of waves help us understand light?
The amplitude of waves in light helps us understand its brightness or intensity. A higher amplitude means brighter light, while a lower amplitude means dimmer light. This property of light waves allows us to perceive and measure the brightness of objects and the intensity of light sources.
What was the original intensity of the light assuming it started out unpolarized?
The original intensity of unpolarized light is the total intensity of light waves vibrating in all possible directions.
How does the amplitude of waves contribute to our understanding of light?
The amplitude of waves in light affects its brightness and intensity. A higher amplitude corresponds to a brighter light, while a lower amplitude results in dimmer light. By understanding the amplitude of light waves, we can interpret the brightness and intensity of light sources.
What are characteristics of amplitude?
Amplitude is the measure of the magnitude of a wave, representing its maximum displacement from the equilibrium position. It is a scalar quantity and is always a positive value. Amplitude determines the intensity or loudness of a wave in sound waves and the brightness or intensity of a wave in light waves.
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

What is the light intensity formula and how can it be used to measure the brightness of a light source?
The light intensity formula is I P/A, where I is the intensity of light, P is the power of the light source, and A is the area over which the light is spread. This formula can be used to measure the brightness of a light source by calculating the intensity of the light emitted per unit area. The higher the intensity value, the brighter the light source is perceived to be.
Why does coherent light have a relatively constant intensity?
Coherence relates to the physics of waves. Specifically, it refers to a property that allows constant interference. Because interference varies the intensity of light, coherent light has a relatively stable intensity.
Why do scientists measure light intensity?
to know how is the light heavy
How does amplitude affect light intensity?
Amplitude of light waves directly affects the intensity of light. As the amplitude increases, more energy is carried by the light wave, resulting in higher intensity. Conversely, a decrease in amplitude leads to lower light intensity.
What are strong light waves?
Strong light waves refer to light waves that have a high intensity or brightness. These waves have a higher amplitude and carry more energy compared to weaker light waves. Strong light waves can be produced by sources such as the sun, lasers, or powerful light bulbs.
The measure of intensity in LIGHT?
The SI unit for luminous intensity is candela (cd).
