LED Refraction Tank Portable

Description

This 90 mm diameter refraction tank contains water and is equipped with a source that emits light linearly.
By tilting the main body, the angle of incidence of light is changed and the reflection and refraction of light occurring at the boundary surface of the water and air can be observed. A linear LED (high brightness red) is mounted on the light source, and the optical path can be clearly observed even in bright classrooms.

Size: 170 x 100 x 35 mm (body),  90 x 20 mm (water tank)
Light source: linear LED (high brightness red)
Power: 2 AA batteries (sold separately)
Accessories: scale plate (for angle, one each for refractive index measurement)
