Question

please tell the correct answer of both​

Answer 1

Answer:

1 .The image in a pinhole camera has the following characteristics:

• The image in a pinhole camera is inverted (upside down) as compared to the object
• The image in a pinhole camera is real (because it can be formed on a screen).
• The image in a pinhole camera is of the same colour as the object.

2. 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.

Answer 2

Answer:

Here is your answer

Explanation:

Ans 1

Pinhole Camera Image Characteristics

A real image is obtained as the image is obtained on the screen.

The size of the image obtained is comparatively smaller than the actual object.

The image is inverted on the x-axis as well as on the y-axis.

The image can be used in the analysis of the rectilinear propagation of the light.

Ans 2

We do not see the shadow of a bird flying high up in air because in their shadow, the umbra is absent and the penumbra is too large and too faint that it is not visible as the distance of screen (i.e. earth) is very large from the object (i.e. bird).
