v21:
updated to ionic 4
added compare button with real data from internet
v13:
automatically asked for camera permission
to be used with a 3D printed attachment see screenshots
position attachment in front of the back camera
take a photo of the light spectrum from sunlight and click the ruler to analyze the emission spectrum
a comparison of the camera data and Wikipedia theoretical image
take a photo of the light spectrum from a normal lamp and click the ruler to analyze the emission spectrum
v6:
Physical Apparatus needed to use App
A diffraction grating to be placed in front of the camera
A light source such as a multi propose laser pointer
Handphone with App/Chrome Browser or a laptop with a camera
recorded to work better now
added back camera
added calibration of known zeroth and first-order diffraction light of the RED laser.
added auto find light
current version 4
some phones/Android OS (XiaoMi etc) may require App permission for CAMERA to be turn on.
some phones/Android OS (Samsung) could be automatic.
close the App and restart App again, it should now detect the given CAMERA permission.
