Question

Why is the shadow of an aeroplane not formed on the Earth surface​

Answer 1

Answer:Shadows are formed when the light gets obstructed by an opaque object. ... When the bird is flying high in the sky the distance between the body and the surface of the Earth is too large and hence even though the light is obstructed by the bird's body it cannot cast its shadow due to the large distance

Explanation:

Answer 2

The shadow of an aeroplane is not formed on the Earth's surface​ as the aeroplane is quite far from the ground to cast its shadow.

Explanation:

• Any opaque object that comes in the path of light casts its shadow.
• This is because the path of the light is obstructed by that object.
• The formation of shadow by opaque objects depends upon the distance between the object and the screen on which the shadow is formed.
• In the case of aeroplanes, the screen is ground.
• The aeroplanes fly at a very high altitude from the ground. Thus, the distance of the aeroplanes from the ground is very large.
• Even though the light is obstructed by the flying aeroplane, it does not cast its shadow.
• This is due to the large distance of the aeroplane from the ground.
• Moreover, the light coming from sideways of the aeroplane reach the earth at the place where the shadow of the aeroplane should be formed on the ground.
• Thus, due to the large distance between the aeroplane and the ground, its shadow is not formed on the ground.
