Question

The customer has asked a lot of questions about Blu-ray disc players and has told you that he understands the benefits of Blu-ray disc versus standard DVD's. You excuse yourself for a few minutes to help another customer while he reads over the extended service policy for the one that best fits his needs. When you come back, he still seems a bit unsure. The associate should respond with:

Answer 1

A Blu-Ray player can read more information than a CD player due to the smaller and more closely packed pits on a Blu-Ray disc. This is achieved using a blue laser with a shorter wavelength.

Step-by-step explanation:

A Blu-Ray player is able to read more information than a CD player because of the difference in the size and spacing of the pits on their respective discs. Blu-Ray discs have much smaller and more closely packed pits than CDs, allowing for a higher storage capacity. The Blu-Ray player uses a blue laser with a short wavelength of 405 nm to read these smaller pits, while a CD player uses a red laser with a longer wavelength. This difference in laser light enables the Blu-Ray player to access more data on the disc and provide higher quality audio and video.
