DVDs and Blu-ray disks store information in patterns that are read by laser light. The shorter the wavelength of the light, the
closer the data tracks can be placed on the disk.Part AA Blu-ray player uses violet light; a DVD player uses red light. Which disk can store more information?Drag the terms on the left to the appropriate blanks on the right to complete the sentences.Terms:DVDVioletRedBlu-ray Disk400nm700nmSentences to fill in:The wavelength of red light is around BLANK, whereas the wavelength of violet light is around BLANK. Since BLANK light has a smaller wavelength the data tracks on a BLANK can be spaced closer together and the BLANK can store more information.
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.
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.
