Extended sources of light are used in the division of amplitude because they provide a coherent and uniform illumination over a larger area, which enhances the visibility of interference patterns. This allows for better resolution and accuracy in experiments, such as those involving diffraction or interference, since the light interacts with the sample or optical elements more uniformly. Additionally, using an extended source minimizes the effects of individual point source variations, leading to more stable and reproducible results.

What is the difference between a shadow formed by a point source of light and a extended source?
A shadow formed by a point source of light has distinct, sharp edges due to the single light source, while a shadow formed by an extended source has softer, less defined edges because light is coming from multiple directions. The point source produces a single, intense shadow, while the extended source creates a more diffused shadow.
Why is the sun an extended source of light?
The Sun is considered an extended source of light because it emits light from a large surface area rather than a single point. This means that the light it produces comes from various points on its surface, creating a more diffuse illumination. As a result, sunlight is not concentrated in a single direction but spreads out over a wide area, contributing to its classification as an extended source. This characteristic affects how shadows are cast and how light interacts with objects on Earth.
What do we see that the amplitude of a wave produces?
The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
ShadoW formed by an extended source?
A shadow formed by an extended source appears fuzzy with indistinct edges due to partial blocking of light from multiple directions. The shadow's edges may exhibit a gradient of light intensity instead of a sharp boundary seen in shadows from point sources.
What is extended light source?
An extended light source is a type of illumination that emits light from a larger area rather than a single point. This can create softer shadows and more uniform lighting, making it ideal for applications in photography, cinematography, and various optical experiments. Extended light sources can include natural sources like the sun or artificial sources such as fluorescent tubes and LED panels. Their characteristics can significantly influence the visual quality and perception of scenes and objects being lit.
How does amplitude of a wave relate to the brightness of the light?
The amplitude of a wave is directly related to the brightness of light; higher amplitude corresponds to greater intensity or brightness. In the context of light waves, greater amplitude means that more energy is carried by the wave, resulting in a brighter perception of light to the human eye. Conversely, lower amplitude results in dimmer light. Thus, amplitude is a key factor in determining how bright a light source appears.
What is an extended source of light?
An extended source of light refers to a light source that is not a point source, meaning it has a finite size and emits light over an area rather than from a single point. Examples include fluorescent tubes, incandescent bulbs, and the sun.
Can I change the amplitude of light waves and if I can how?
Yes, you can change the amplitude of light waves, which affects their intensity or brightness. This can be achieved by using various methods such as adjusting the power of the light source, employing filters to attenuate the light, or modulating the light with devices like amplitude modulators. In practical applications, varying the amplitude is often used in communication systems and lighting control.
What does amplitude determine in light?
amplitude will determine the brightness in light or the loudness in sound.
What does the amplitude of a light wave determine?
The amplitude of a light wave shows the light's brightness relative to waves of similar wavelength.
How does amplitude affect a light wave?
The amplitude of a light wave affects its brightness or intensity. A higher amplitude corresponds to a brighter light, while a lower amplitude results in a dimmer light.
What property of light is reflected by the amplitude of a light wave?
The brightness or intensity of light is reflected by the amplitude of a light wave. A greater amplitude corresponds to brighter light, while a smaller amplitude corresponds to dimmer light.
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 does the amplitude of a light wave determine your perception of?
The amplitude of a light wave determines the brightness or intensity of the light that you perceive. A higher amplitude corresponds to brighter light, while a lower amplitude corresponds to dimmer light.
What is the difference between a shadow formed by a point source of light and a extended source?
A shadow formed by a point source of light has distinct, sharp edges due to the single light source, while a shadow formed by an extended source has softer, less defined edges because light is coming from multiple directions. The point source produces a single, intense shadow, while the extended source creates a more diffused shadow.
What will happen if a point source is used instead of extended source in Newton's ring experiment?
The rings may formd but the lack of intensity of light,the dark and light rings are not vissiable very well..
Why is the sun an extended source of light?
