Student Basic Set – Optics / Atomic physics – Digital Set – 16 Experiments

ABOUT THIS PRODUCT:

Function and Applications

Equipment set allowing the performance of 17 experiments about the following topics:

• Spectroscopic analysis (2 Experiments)
• Diffraction on a grating (1 Experiment)
• Diffraction on everyday life’s objects (2 Experiments)
• Absorption and fluorescence (3 Experiments)
• h-Determination with light emitting diodes (1 Experiment)
• Bandgap of semiconductors (1 Experiment)
• Investigation of solar cells and photodiodes (2 Experiments)
• Electric and optical properties of LED (2 Experiments)
• Polarisation of light (3 Experiments)

In 10 experiments, you can use the Cobra SMARTsense sensors Current and Voltage in combination with tablets (iOS and Android) and smartphones (Android) instead of the classic measuring device.

Benefits

• The ideal combination of classic experiments (practical competence) and digital data acquisition (media competence)
• Individual teaching structure possible: you can decide to choose the measuring instrument you want (classic or digital)
• Future-proof: Prepare the transition to the digital school today
• Perfectly matched to digital science lessons with tablets and smartphones
• Faster and higher learning success: The use of digital devices increases the identification and thus increases the motivation of the students
• Matched with international curriculum
• Quantum and / or wave optics in student experiment
