- Optics Experiment Kit is perfect to help kids learn various properties of lenses and also will help them how to calculate the angle of incidence, angle of reflection, angle of refraction, and focal lengths of the lenses.
- The Best Kids experiment kit, where "Learning is Fun".
- A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction.
- Lenses are used in various imaging devices like telescopes, binoculars, and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia.
- Optics Experiment Kit can be used for proving the law of reflection. The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. When the beam of light using the device is directed on the reflective surface, you can measure the angles and compare the angle of incidence and angle of reflection.
If the lens is biconvex or plano-convex, a collimated beam of light passing through the lens converges to a spot (a focus) behind the lens. In this case, the lens is called a positive or converging lens.
If the lens is biconcave or plano-concave, a collimated beam of light passing through the lens is diverged (spread); the lens is thus called a negative or diverging lens. The beam, after passing through the lens, appears to emanate from a particular point on the axis in front of the lens.
- Optics Experiment Kit comes with a variety of lenses that are made of plastic and a battery-operated laser console (battery not included).
- The box has a chart to measure various angles of the beam of light. The light beam is controlled by a switch that can be used with different lenses to perform different experiments as shown in the images.
