Setup

Navigate to the website https://iwant2study.org/ospsgx/index.php/interactive-resources/physics/04-waves/03-electromagnetic-spectrum/643-datalogger and click on the latest thumbnail
prepare the physical apparatus needed
discharge lamps, hand phone, diffraction grating setup 3D printed , rubber
on the hand phone it should look like this, agree to let Chrome mobile take video and sound if prompted
fix the diffraction grating using a rubber to the back camera of the phone as shown
fix a lamp on the discharge lap setup and turn it on, say first lamp is Helium
point the camera with the diffraction grating on the table, make sure the fluorescent lamp on the room is able to the captured through the grating as a reference light spectrum source pattern
click calibrate
after clicking calibrate, the display will show the fluorescent lamp spectrum as the light from the fluorescent lamp came through the diffraction grating intot he camera to produce this image
click identify
after identify, point the camera with the diffraction grating as a new light source say the Helium lamp discharge
click confirm button
after confirm,
click compare to compare with our results from the internet as possible answers.
while doing the new light, make sure not to shift the diffraction grating position from the camera on the phone else, need to re-calibrate with fluorescent light again
Next light source say mercury, click identify
aim the camera through the diffraction grating to get a light emission spectrum and click identify
after identify, the screen may say something like mercury found
click compare and see the line emission lines from phone (above) to the picture resource from internet (below)
next, try Neon lamp
click on the identify and aim the camera on the lamp
click compare to see the result from the camera (above) and the resource of the internet (below)
so it is possible to use the phone via our webpage to gather emission spectrum and even identify some of the common gases in our database.
