Reflection of Light

Reflection of light is a phenomenon that occurs when light rays bounce off a surface and return back to the original medium. This phenomenon is responsible for various optical phenomena that we observe in our daily lives. One such example is the image of the sun visible on the surface of water, as mentioned in option 'A'.

Explanation

When light from the sun falls on the surface of water, the rays get reflected. This reflection occurs because water is a smooth and shiny surface. The rays of light bounce off the water surface and create an image of the sun. This image appears as a bright spot on the water, resembling the shape and size of the sun. It is important to note that this is not the actual sun, but a reflection of it.

This phenomenon can be observed on calm water bodies such as lakes, ponds, or even a glass of water. When the water surface is disturbed, such as by waves or ripples, the reflection of the sun may appear distorted or broken.

Other Options

Let's briefly discuss the other options mentioned in the question and their relation to the reflection of light:

b) Reddish color of the sky during evening: This is not directly related to the reflection of light. The reddish color of the sky during the evening is caused by the scattering of sunlight by the Earth's atmosphere. The shorter blue and green wavelengths are scattered more, leaving the longer red wavelengths to dominate the sky.

c) Sun is visible two minutes before the actual sunrise: This phenomenon, known as atmospheric refraction, occurs due to the bending of light as it passes through the Earth's atmosphere. The atmosphere acts as a lens, bending the light rays and allowing us to see the sun slightly before it actually rises above the horizon.

d) Greenhouse effect caused by the radiation of the sun: The greenhouse effect is not directly related to the reflection of light. It is a process in which certain gases in the Earth's atmosphere trap the heat radiated from the Earth's surface, leading to a warming effect.

In conclusion, the phenomenon related to the reflection of light mentioned in option 'A' is the image of the sun visible on the surface of water.

Reflection of Light

Introduction:
The phenomenon related to the reflection of light refers to the way light behaves when it encounters a surface and bounces back. This process is called reflection and it plays a crucial role in our daily lives. It helps us see objects, allows us to see our own reflection, and is responsible for various optical illusions and phenomena.

Explanation:
The given options are related to different optical phenomena, but only option A, the image of the sun visible on the surface of water, specifically describes the reflection of light. Let's explore this phenomenon further.

Image of the Sun Visible on the Surface of Water:
When light from the sun falls on the surface of water, it undergoes reflection. The smooth surface of the water acts as a mirror and reflects the light rays. This reflection forms an image of the sun on the water's surface, which is visible to us. The image appears to be similar to the actual sun, but it is inverted, meaning the top of the image is at the bottom and vice versa.

Key Points:
- When light rays hit a smooth, reflective surface like water, they bounce back, forming an image.
- The image formed is inverted compared to the actual object.
- This phenomenon can be observed when looking at a pond, lake, or any other body of water on a sunny day.
- The intensity and clarity of the image depend on the smoothness of the water's surface. Calm water surfaces produce clearer and more distinct images.

Other Options:
It is important to note that while the other options mentioned in the question are related to different optical phenomena, they do not specifically describe the reflection of light.

- Option B mentions the reddish color of the sky during the evening, which is caused by the scattering of sunlight due to the Earth's atmosphere.
- Option C refers to the sun being visible two minutes before the actual sunrise, which is due to the bending of light by the Earth's atmosphere.
- Option D explains the greenhouse effect caused by the radiation of the sun, which is a different phenomenon related to the absorption and trapping of heat by certain gases in the atmosphere.

Therefore, the correct answer to the given question is option A, the image of the sun visible on the surface of water, as it specifically describes the phenomenon of reflection of light.
