Select Open FX and drag Light Rays on your clip.

Increase the length and make sure to adjust the position of the ray.

so it’s coming from the source of the light.

What is Light Rays?

Light rays are the paths along which light travels through space. Light rays are a fundamental concept in optics, which is the branch of physics that deals with the behavior and properties of light.

In the simplest terms, a light ray can be thought of as a straight line that originates from a light source and travels in a particular direction until it encounters an obstacle or is absorbed. However, in reality, light can also bend, reflect, refract, and scatter as it interacts with different materials and surfaces.

The behavior of light rays is determined by several factors, including the properties of the light itself (such as its wavelength and polarization), the characteristics of the medium through which it is traveling (such as its refractive index and density), and the geometry of the surrounding environment (such as the shapes and positions of mirrors and lenses).

Understanding the behavior of light rays is essential in many fields, such as
