Incorrect Statement: Sun is visible 2 minutes after sunrise and 2 minutes before sunset
Explanation:
The statement that the sun is visible 2 minutes after sunrise and 2 minutes before sunset is incorrect.
Sunrise and Sunset:
Sunrise is the moment when the upper edge of the sun appears on the horizon in the morning, marking the beginning of daylight. Sunset, on the other hand, is the moment when the upper edge of the sun disappears below the horizon in the evening, marking the end of daylight.
Atmospheric Refraction:
Atmospheric refraction is the bending of light as it passes through the Earth's atmosphere. This bending of light is responsible for various optical phenomena, including the apparent shift in the position of the sun during sunrise and sunset.
Why the Sun is Visible Before Sunrise and After Sunset:
During sunrise and sunset, the sun is actually below the horizon. However, due to atmospheric refraction, the light from the sun bends as it passes through the Earth's atmosphere and reaches our eyes, making the sun appear higher in the sky than it actually is. This phenomenon is known as the apparent sunrise and sunset.
The amount of atmospheric refraction depends on several factors, including the density of the atmosphere and the angle at which the sunlight enters the atmosphere. The refraction is greater when the sun is closer to the horizon, causing the sun to appear higher than its actual position.
Duration of Sun Visibility:
The duration of sun visibility before sunrise and after sunset varies depending on the geographical location and time of the year. It is generally longer near the equator and shorter towards the poles.
In reality, the sun becomes visible approximately 5 to 10 minutes before the actual sunrise and remains visible for a similar duration after the actual sunset. The exact duration may vary depending on atmospheric conditions and the observer's location.
Therefore, the statement that the sun is visible 2 minutes after sunrise and 2 minutes before sunset is incorrect.
