A simple means is to use a mirror (or some other reflective material). A ray of light will reflect and refract to varying degrees as it interacts with surfaces.
You can apply basic geometry with optics laws to see how you can change the path of a ray of light. Snell's Law gives the relationship between direction and different surfaces.
A more interesting means of changing light direction involves something about black holes. May be their distortion of space or time, or simply their apparent vast gravity. I believe we've managed to show that phonons (light) have mass, so you could use gravity to deflect them. I'm pretty sure photons also have magnetic and electric fields, so a sufficiently radical magnetic field would be handy too.
Now, to pick on your choice of words, light "can" change direction any time something that changes its direction occurs. In other words, it's not a function of time.
What else can I help you with?
How do i change a direction of a light beam?
To change the direction of a light beam, you can use mirrors or lenses to reflect or refract the light in the desired direction. Adjusting the angle of the mirror or lens will change the direction of the light beam. Alternatively, you can physically move the light source or the object the light is reflecting off of to change the direction of the beam.
Why does light change direction when it hits things?
Light changes direction when it hits a shiny surface
When light waves slow down do they change direction?
When light waves slow down as they travel from one medium to another, such as from air to glass, they do change direction. This change in direction is called refraction and occurs due to the change in speed of the light waves in the new medium.
What causes light to change directions?
The change in speed of light changes the direction.
When light is reflected does the direction of the light wave change?
Yes, the light wave goes in the direction of the angle or reflection.
What is the name given to a change of direction of a ray of light?
The name given to a change of direction of a ray of light is called refraction. Refraction occurs when light passes from one medium to another with a different optical density, causing the light ray to bend.
When light is refracted there is a change in its?
direction and speed.
What is the name of the effect when light changes direction?
Reflection-when light change the direction of motion within same medium. Refraction-change of direction when moving to another medium.
What is reflection for light?
A shining or polished surface changes the direction of light.This change in direction is called reflection of light.
A lens makes the light change direction what is the change of direction called?
Scattering is an interaction of light with matter that causes light to change its energy, direction of motion, or both. so the plain answer is scattering the particles.
When light bounces off the surface of an object the light is in a different direction?
Yes, when light bounces off the surface of an object, it undergoes reflection which results in a change in the direction of the light. This change in direction is determined by the angle of incidence and the angle of reflection, according to the law of reflection.
How could you change the direction of a ray of light?
You can change the direction of a ray of light by reflecting it off a surface, refracting it through a different medium, or diffracting it through an obstacle. The change in direction depends on the angle of incidence and the properties of the material it interacts with.
