Description

Photoelectric Effect Planck's Digital MetersThe Photoelectric Effect Planck's Digital Meters device enables precise measurement of current and voltage, making it ideal for experiments related to the photoelectric effect and the study of Planck's constant in physics. A. Lamp and Filters The Photoelectric Effect Planck's Digital Meters include two displays: one shows the current through the Photo Tube in 0. 1 nanoamps, while the other shows the backing volts required to bring the current to zero.

The Photoelectric Effect Planck's Digital Meters device enables precise measurement of current and voltage, making it ideal for experiments related to the photoelectric effect and the study of Planck's constant in physics.

A. Lamp and Filters

The Photoelectric Effect Planck's Digital Meters include two displays: one shows the current through the Photo Tube in 0.1 nanoamps, while the other shows the backing volts required to bring the current to zero. These simultaneous readings allow for faster and less confusing experiments without the need for switching. The traditional method of using a white light source and color filters is used as the light source.

Kit Includes:

  • 1 Photo-Electric Effect instrument, runs from 9V transistor battery
  • 1 9V battery, type #216
  • 1 Lamp as light source, 12Volt, 25 Watt, mounts on rear of unit
  • 1 set of 5x Color filters, calibrated in nanometers wavelength
  • 1 set 4x Apertures to set the quantity of light from the light source

Aperture orifices: 7mm, 10mm, 14mm, and 20mm diameters One test sheet and Experiment Sheets for using the instrument are included.

B. 5 LEDs

Kit Includes:

  • Set of 5x LEDs of specific wavelength mounted on a small panel with cable & plug, mounts on the rear of the instrument. The LED wavelengths are indicated on a label on the rear face of the instrument
  • Experiment sheets for using the instrument

Most importantly, its drainage system directs water into the tank, keeping it dry.
Color: Black, Size: Medium
This drain rack is small and fits perfectly on the edge of my sink. It's just the right size to hold hand soap and dishcloths, doesn't take up much space, and most importantly, it directs water directly into the sink, keeping it dry and keeping my sink clean and tidy.

Good product
Color: Black, Size: Medium
It is as described, looks neat and tidy on the sink. Just big enough to do what I need it to do. My sink stays dry because the wate goes back int the sink.

It is almost great.
Color: Black, Size: Medium
It is a nice sponge holder but the tray is not wide enough and it falls. Because it was the only one I found with a spout, I am keeping it, and figured a way to stick it so the tray doesn't fall. The other thing is that the tray is not sunken enough in the middle for all the water to be routed there, and the spout doesn't always get rid of all the water inside, so once in a few days, I have to manually press it down and more water comes out. The dishcloth rack is not great for cloths, they get wet. Other than that, it looks very nice, it is aesthetic, big enough for all my kitchen stuff, and makes my kitchen neater, so I like it.

Love this product very convenient
Color: Silver, Size: Medium
This was great to keep all my brushes, cloth, detergent and scrubby together and neat. I love the drainage and it looks clean. The only thing I don't care for is the bar that holds the cloth comes off all the time. Other than that it is great.
