It doesn't always travel in straight line! Light can be bent by objects of very large mass (for instance, when it passes by a star) by gravity. It is also bent when the medium it is passing through changes index of refraction.
Otherwise, it does travel in a straight line. Although to be honest, I'm not entirely sure "how" we know that! Good question! Anybody?
But you do know if the thing seen is really in the position that it appears to be.
How do know that it travels in a straight line?
Because people cant see around bends and you need light to see so light cannot bend
What else can I help you with?
Are straight-line winds as dangerous as a tornado?
Straight-line winds can be as dangerous as a tornado because they can cause significant damage and destruction to buildings and structures. However, tornadoes are typically more powerful and can cause more widespread devastation compared to straight-line winds.
What causes a shadow?
Light travels in straight lines. A shadow is caused when light beams hit an object and bounce off, preventing the light beams from passing through and hitting the ground on the other side. So when you, for example stand in the sun and the suns rays hit you, the light reflects off you and goes the other way. so behind you no light falls from the direct rays of the sun, so it is dark. The area around your shadow is where the light is hitting and reflecting, so technically speaking there is shadow under them, which is why we associate the ground with being dark. no light.
Why doesn’t lightning travel in a straight line?
So it’s kind of a complicated process, but here’s the two-sentence version: Lightning is an electric current that takes the path of least resistance from the base of a cloud to the ground. Since the air it travels through is not uniform—variations in things like temperature, humidity, and pollutants determine how resistant air is to the charge—the lightning has to zig and zag to stay on that path.
How does a fireplace heat a room and why do only the people directly in front of the fireplace feel the warmth of the fire?
A fireplace heats a room by radiating heat in all directions. People directly in front of the fireplace feel the warmth more because they are closer to the source of heat and receive more radiant heat energy. The further away you are from the fireplace, the more the heat dissipates and the less warmth you feel.
What are the key differences between tornadoes and straight line winds in terms of their formation and impact on the environment?
Tornadoes are rotating columns of air that form from severe thunderstorms, while straight line winds are strong, non-rotating winds that move in a straight line. Tornadoes can cause more localized and intense damage, with their spinning motion often resulting in more destruction in a concentrated area. Straight line winds, on the other hand, can cause widespread damage over a larger area due to their strong and consistent force.
What property of light best explain your observation?
The observation that light travels in a straight line can be explained by the property of light known as rectilinear propagation. This property states that light travels in a straight line in a homogenous medium.
Why do light travels in straight line?
It does not, it travels as a wave
What is the straight line which light travels in a straight line called?
Trajectory
What kind of light travels in a straight line?
Visible light travels in a straight line unless it encounters obstacles or mediums that cause it to bend or scatter.
What travels in a straight line and travels the fastest?
Light the electromagnetic wave.
Does light travels in straight line?
Light typically travels in a straight line, as described by the principle of rectilinear propagation. However, it can be affected by gravitational fields or optical illusions that may make it appear otherwise.
Is a shadow proof that light travels in a straight line?
Yes, a shadow is proof that light travels in a straight line because shadows are formed when an object blocks light that is traveling in a straight path from the source to the surface where the shadow is cast. If light did not travel in a straight line, shadows would not form as they do.
What kind of wave does light travel in?
I have the straight answer from the Internet and my science teacher that light travels in the motion of waves.
Which travels in a straight line sound light electricity?
Electricity.
A narrow beam of light that travels in a straight line is a?
A laser
What shape does light travel at?
Light travels in a straight line, moving in a straight path known as a ray.
Why does light travel straight?
light travels in a straight line because it can only be bend by reflective objects.
