D503,With reference to Visible Light Communication (VLC) technology, which of the following statements are correct? (1) VLC uses electromagnetic spectrum wavelengths 375 to 780 nm. (2) VLC is known as long-range optical wireless communication. (3) VLC can transmit large amounts of data faster than Bluetooth, (4) VLC has no electromagnetic interference. Select the correct using the code given below: (a) 1, 2 and 3 only (b) 1, 2 and 4 only (c) 1, 3 and 4 only (d) 2, 3 and 4 only
This is prelims 2020 quesiton

I would go with C. The reasoning is that since it's visible light communication, it can't be long range. If there are physical obstacles, the light wouldn't be able to penetrate through them and so long range communication wouldn't be possible using visible light.

This relates to LiFi that was in news last year. Statement 4 is wrong because light which consists of photons carry no charge/mass and is not affected by EM interference. If it were affected, light would bend around magnets.

Should be C no? LiFi and associated technologies ka major limitation is that they are short range. Eliminating 2 leaves C.
