Some questions about humidity and storing DVDs in a closed cardboard ... This discussion centers on the effects of humidity on storing DVDs and electronic components in closed cardboard boxes. It highlights that moisture can enter these containers during humid weather, and questions whether transitioning to a hot and dry climate (31-35°C) will evaporate the moisture from the items inside.

What is v(dv/dx) and how does it relate to acceleration? The discussion centers on modeling acceleration using the expression v (dv/dx), which is derived from the chain rule in calculus. This formulation allows for the analysis of motion in one dimension, where v represents velocity as dx/dt. The relationship between v (dv/dx) and acceleration (a) is established as v (dv/dx) = dv/dt = a. This approach is particularly useful in scenarios involving ...

Question about plastic bags and humidity • Physics Forums Additionally, it was noted that DVDs are classified as MSL-1, meaning they are not significantly harmed by humidity. Recommendations included using airtight vacuum storage bags and desiccant packs to ensure dryness.

Study "Optical physics: Depth of Field and its applications" Explore "How data is encoded and read on DVDs and CDs" Learn about "Opto-electronic devices and their role in data retrieval" Optical engineers, hardware developers, and anyone interested in the technical workings of dual layer DVDs and optical data storage technologies.

Why is there a spectrum on the back of a CD or DVD? The spectrum observed on the back of a CD or DVD is a result of diffraction, where the tracks and sectors on the disc act as a diffraction grating. This phenomenon occurs when light bends around the edges of these microscopic structures, leading to the overlapping of various colors in a continuous spectrum. The discussion confirms that the correct explanation for this visual effect is indeed ...

CD Players: How Do They Interfere? - Physics Forums The "reference beam" in the case of CDs and DVDs is the part of the laser beam that is reflected from the surface of the disk (aka the "land"). THe beam that goes into the pits will travel a total extra distance of 1/2 a wavelength through the plastic (so the depth of the pit must be 1/4 wavelength in the plastic).

Rainbow light reflection on TV from my hand • Physics Forums The phenomenon of rainbow light reflection on a TV screen from a hand is primarily attributed to the TV acting as a diffraction grating. The white light reflected from the hand is dispersed into various colors due to the pixel grid's fine spacing, similar to effects seen with CDs and DVDs. The discussion highlights the role of thin film interference and refraction in this optical effect ...

Kinematics equations: Prove that a=vdv/ds • Physics Forums The discussion centers on proving the equation a = v dv/ds, where a represents acceleration, v is velocity, and s is displacement. The participants clarify that velocity v is a function of time and space, specifically v = v (x, t), and emphasize the importance of using the chain rule for differentiation. They conclude that while velocity is not constant, it can be expressed as a function of ...

How to load programs to computer without a CD or DVD drive. This discussion provides a comprehensive guide on how to load programs onto a laptop without a CD or DVD drive by creating and using ISO image files. Users can create an ISO file from a DVD using software like BurnAware and then mount this ISO on their new laptop using virtual drive tools such as Daemon Tools Lite. The process involves creating an ISO image, mounting it to a virtual drive, and ...

Vinyl records, RPMs, and velocity. How does it work? FWIW, CDs and DVDs are recorded with the disk moving at a constant linear speed, and the rotation speed does change while the disk is playing. Because the data is recorded digitaally, it is easy for the player to "measure" how fast it is playing the disk, and so the rotation speed of a CD is actuallly controlled by the disk that is being played.
