The bright central LED is actually 3-in-1 and includes separately controlled red, green and blue (RGB) sources. This allows you to teach the technology of color with powerful lessons that apply to many technologies such as LCD screens, digital cameras, video, and fiber optic communications.

Newton's experiments with prisms led to the understanding that natural (white) light is composed of a range of differently coloured beams.

For example, when you shine white light into a prism, you observe a band of colours on the other side. This process isn't magic, but rather a scientific phenomenon known as dispersion of light.

A key component of the Essential Physics Light and Optics module, this rechargeable light source has four colored LEDs at the edges and a powerful RGB LED in the center. It also connects directly to your devices and streams data via Bluetooth 4.

Light slows down and refracts or changes direction when it enters the prism. When it exits, it speeds up and refracts away from the normal. Different colors of light refract differently because they have different refractive indices, causing white light to split into a spectrum of colors.

The rainbow effect in a prism is explained by the phenomenon of dispersion of light into different colours, with each colour, or wavelength of light, bending at a different angle.

A light prism is a transparent optical element with flat, polished surfaces that refract, or bend, light. It's typically a polished glass triangle and the light waves passing through it are both slowed and bent.

Newton's experiments with prisms in the 17th century led to a deeper understanding of the nature of light, proving that natural (white) light is composed of a range of differently coloured beams. This was a significant leap in the scientific understanding of light.

The rechargeable light source lasts all day and you never need batteries! The four colored LEDs (R/Y/G/B) on a 10 mm spacing make it easy to make precise magnification measurements and see image inversion.

The Wireless Light Source has been discontinued and is no longer available for purchase. PASCO recommends the following alternative:Basic Optics Light Source (OS-8470)

The light source makes a perfect illuminated “object” for optics experiments, and the fixed spacing of the colored LEDs makes it easy to observe and measure image properties such as magnification, inversion, and brightness.

Different prism angles and materials lead to variation in how dispersed or close the bands of colours are. This means the refraction and hence the spectrum witnessed can vary based on the properties of the prism.

In the domain of optics, a light prism is a transparent optical element with flat, polished surfaces that refract, or bend, light. Its form is typically a polished glass triangle and the light waves passing through it are both slowed and bent.
