Final answer:
Correct statements regarding Visible Light Communication (VLC) are that it uses wavelengths approximately between 380 to 760 nm, can be faster than Bluetooth in data transmission and has low electromagnetic interference. VLC is not known for long-range communication, which makes option (c) 1, 3, and 4 only the correct answer.
Step-by-step explanation:
With reference to Visible Light Communication (VLC) technology, the following statement can be evaluated for accuracy:
VLC uses electromagnetic spectrum wavelengths 375 to 780nm.
VLC is known as long-range optical wireless communication.
VLC can transmit large amounts of data faster than Bluetooth.
VLC has no electromagnetic interference.
Based on the information provided:
The range of visible wavelengths is indeed approximately 380 to 760 nm, so statement 1 is correct.
VLC is not typically known for long-range communication; it is usually limited to shorter ranges due to the nature of light propagation, making statement 2 incorrect.
Considering data transmission rates, VLC can indeed transmit large amounts of data and can be faster than Bluetooth, thereby making statement 3 correct.
As for statement 4, VLC typically has very low electromagnetic interference when compared to other wireless technologies, which can make it advantageous in certain environments, thus making statement 4 correct.
Therefore, the correct option from the choices provided, considering the 500 mention correct option in both part guideline, is option (c) 1, 3, and 4 only.
