  2. Trees

  3. Plants

  4. Gaps in leaves

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When sunlight passes through the leaves of trees, we are able to see the circular images of the sun. It is the gaps in the leaves which act as a pinhole camera and produce an image of the sun.

Multiple choice
  1. Erect

  2. Magnified

  3. Virtual

  4. Inverted

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The image formed by a pinhole camera is real, upside down, i.e. inverted and a clear or a sharp one (size of the pinhole should be quite small). 

Multiple choice
  1. Silver bromide

  2. Potassium nitrate

  3. Hydrogen peroxide

  4. Hydrogen sulphide

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Silver bromide is light-sensitive and is the key compound in traditional photographic film and paper. When exposed to light, it undergoes a chemical change that creates the latent image, which is then developed to produce the visible photograph.

Multiple choice
  1. Right side up and reversed from left to right

  2. Upside down and reversed from left to right

  3. Right side up and not reversed from left to right

  4. Upside down and not reversed from left and right

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A camera lens forms a real, inverted image on the film/sensor plane. This means the image is both upside down (inverted vertically) and reversed from left to right (inverted horizontally). This is how all simple lenses form real images.

Multiple choice
  1. a shadow

  2. an image

  3. both a shadow and an image

  4. neither a shadow nor an image

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A pinhole camera refers to a device which is used by making a hole in the cardboard (close box) for the entry of light from one point. The other surface side of the camera is having a tracing paper pasted on it      which acts as screen. When light enters through hole after getting striked from an object, then it undergoes internal reflections to create the image of that object on the tracing paper acting as screen.
