Question

Directions: In the following questions, the Assertions (A) and Reason(s) (R) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
(A) Both the Assertion and the Reason are correct and the Reason is the correct explanation of the Assertion.
(B) The Assertion and the Reason are correct but the Reason is not the correct explanation of the Assertion.
(C) Our Assertion is true but the Reason is false.
(D) The statement of the Assertion is false but the Reason is true.
(E) Both the statements are false.

1. assertion; blue colour of light appears due to scattering of white light
reason; blue colour has shortest wavelength in visible spectrum and the colour which has the shortest wavelength scatters the most
2.assertion; agbr is used in photographic films
reason; agbr is photosensitive and changes to ag and br in precense of sunlight and undergoes decomposition reaction

Answer 1

Explanation:

HEY! MATE ❤

HERE IS YOUR ANSWER ❤

1. A : BOTH THE ASSERTION AND REASON ARE CORRECT AND THE REASON IS THE CORRECT EXPLANATION OF THE ASSERTION

2. same as above explanation :

Answer 2

1. A. Both the assertion and the reason are correct and the reason is the correct explanation of the assertion.

2. A. Both the assertion and the reason are correct and the reason is the correct explanation of the assertion.

Analysis

• In the VIBJYOR spectrum, blue light has the shortest wavelength. The light having the shortest wavelength scatters the most. Thus, due to the scattering of the blue light from the white light, we can see the blue color of the sky.

• AgBr is sensitive to sunlight and decomposes into Ag and Br. Ag is silver, and Br is bromine which forms a perfect component for clicking negative pictures. When the light falls on this, it decomposes and darkens the exposed part of the photography. Thus it is used for black and white photography.
