Answer: The Bluray Disk can store more information
The wavelenght of red light is around 700nm, whereas the wavelenght of violet light is around 400nm. Since the violet light has smaller wavelenght the data tracks on a Blu-ray Disk can be spaced closer together and the Blueray Disk can store more information
Explanation: Because a disk work by storing data using bits, the more bits can be stored in one place improves the total storage on the unit. The less the space to storage the bit, the more space overall for the disk.
Answer: The Bluray Disk can store more information.
Answers for blank spaces are:
1) 700nm
2) 400nm
3) violet light
4) Blu-ray Disk
5) Blueray Disk
Explanation: violet light has a shorter wavelenght than red light. Since the disk that uses light with shorter wave can have their data more closely packed, then the Bluray will store more information per surface area.
