Question

Name the radiation which can be detected by a solution of silver chloride.
A. X-ray radiation
B. Ultraviolet radiation
C. Infrared radiation
D. Visible radiation

Answer 1

Hint: One of the given radiations when exposed to solution of silver chloride shows an intense reaction. If we place the solution of silver chloride in the spectrum of radiations, one of the radiations will have an intense reaction with the solution of silver chloride.

Complete step by step answer:
We can answer this question if we know which radiation plays an important role if exposed to silver chloride. The radiation can be detected if silver chloride exposed to this radiation shows an intense reaction.
The types of radiations in the radiation spectrum are:
- Gamma radiations
- X-ray radiation
- Ultraviolet radiation
- Visible rays
- Infrared radiation
- Microwave radiation
- Radio waves

We need to check every given option.

X-ray radiation.
Silver chloride when exposed to X-ray radiations showed no intense reaction. Therefore, the option (A) is incorrect.

Ultraviolet radiation.
Silver chloride placed beyond the visible end of the spectrum shows an intense reaction. The radiation beyond the visible end is ultraviolet radiation. Therefore, the ultraviolet radiations encounter the intense reaction in the silver chloride.

Infrared radiation.
Silver chloride when exposed to infrared radiations showed no intense reaction. Therefore, the option (C) is incorrect.

Visible radiation.
We see visible radiations have no effect on the solution of silver chloride. Therefore, the option (D) is incorrect.

So, the correct answer is “Option B”.

Note:
The ultra means beyond and ultraviolet means beyond the violet end of the visible rays. The ultraviolet rays were discovered by Johann Ritter in his experiment with silver chloride when he was testing the effect of radiations on the solution of silver chloride.
