Question

5. Photomultiplier tube converts
(i) thermal energy into light energy, (ii) thermal energy into electric energy,
(in) light energy into electric energy. (iv) electric energy into light energy.
​

Answer 1

Answer:

light energy into electric energy. (iv) electric energy into light energy.

Answer 2

The answer will be Photomultiplier tube converts (iii) light energy into electric energy.

• Photomultiplier tubes are also known as PMT short and are devices that help detect photons.
• This device utilizes the photoelectric particles along with the secondary emission and converts light energy to electric energy.
• A photomultiplier works by the method of absorbing the emitted amount of light energy.
• Then the device re-emits the absorbed light energy in the form of electrical energy with the help of the photoelectric effect.

Hence, the correct option to be chosen to complete the given sentence will be the Photomultiplier tube converts (iii) light energy into electric energy.
