Investigating photoelectric effect and electron transfer

[CDrappi]

Hey I'm doing a 2 part project. The first part is the photoelectric effect, which I need some help on. I need a foil of metal (like aluminum foil but less of a work function) and a source of energy waves (UV or violet light probably). I need the combo of light source to generate a photoelectric effect. I'm sure you all know the formula, K = hf - Wf where f is frequency, h is Plancks constant and Wf is the work function. So if you can lead me to those things or gce suggestions that would be great. Affordability is critial and I don't want to spend more then 150 on this project. Also, I don't want the light to be to energyful for safety reasons because I don't want cancer

Thanks

for your question! The most affordable way to generate a photoelectric effect is to use an LED light with a low work function metal like zinc or gallium. LEDs are very affordable and you can purchase them online for around $10. Gallium and zinc are also fairly inexpensive and can be found in many electronics stores for around $20 each. Additionally, these metals have low work functions, which makes them ideal for the photoelectric effect. For safety reasons, make sure you are using a low powered LED with a wavelength of no more than 400nm. This should ensure that the light is not too energetic and that you do not risk any damage to yourself or your equipment.

for reaching out about your project on the photoelectric effect. It sounds like you have a good understanding of the formula and what you need for this experiment. Let me provide some suggestions for the materials and safety concerns.

For the foil, you can use a metal like copper or zinc, which have a lower work function than aluminum. These can be easily found at hardware or craft stores for affordable prices. As for the light source, you can use a UV LED light, which emits UV radiation but is relatively safe and affordable. You can also use a violet laser pointer, which can be found for under $20 and emits a specific wavelength of light.

In terms of safety, it is important to follow proper precautions when working with any type of radiation. Make sure to wear protective gear, such as gloves and goggles, and keep the light source at a safe distance from your skin. Also, limit the exposure time and consider using a shield to block any excess radiation.

I hope this helps guide you in your project and I wish you the best of luck! Keep in mind that safety should always be a top priority in any scientific experiment. Let me know if you have any further questions.
