Question

4. Amongst the following statements which
is true for a photosensitive material?
(a) All materials show photosensitivity to
some or more extent
(b) Different photosensitive materials have
same sensitivity
(c) Same photosensitive substances give
different response to light of different
wavelengths
(d) All photosensitive materials give
response to green light

Answer 1

Answer:

The true statement for photosensitive material is a ) option

Answer 2

The correct answer among the given choices is OPTION C: Same photosensitive substances give a different response to lights of different wavelengths.

• The work function of photosensitive substances is extremely low.
• The chemical constitution of a substance changes when it is exposed to electromagnetic radiation.
• When photosensitive compounds are exposed to light, electrons are liberated.
• These electrons were given the name photoelectrons once they were discovered. The photoelectric effect is the name for this phenomenon.
• That's the reason photosensitive material works differently in exposure to different wavelengths.
