What else can I help you with?
Can refraction of light happen without changing the direction of light?
no. Energy is conserved.
Is it possible for a nonzero net force to act on an object without the object's speed changing?
Yes, it is possible for a nonzero net force to act on an object without changing its speed. This can happen if the force is acting perpendicular to the direction of motion, resulting in a change in direction but not speed (as in circular motion).
How can velocity change without changing the speed?
Consider velocity as consisting of a speed, and a direction. If any of the two changes - that is, if either the speed or the direction changes - then the velocity changes.
What are 3 transformations and where they happen?
Three types of transformations are translation, rotation, and reflection. These transformations can occur in a plane, on a grid, or in three-dimensional space. Translation moves an object without changing its orientation, rotation turns an object around a fixed point, and reflection flips an object across a line.
What are three things that can happen to light when it hits a new medium?
Reflection: Light can bounce off the surface of a new medium, changing direction. Refraction: Light can bend or change direction as it passes through a new medium, due to a change in its speed or wavelength. Absorption: Light can be absorbed by a new medium, converting its energy into other forms such as heat.
When will acceleration happen?
Acceleration occurs when an object changes its velocity, either by speeding up, slowing down, or changing direction. It can happen when a force is applied to the object, causing it to accelerate in the direction of the force.
What happen to an object when there is unbalaced force acting on it?
When an object experiences an unbalanced force, it will accelerate in the direction of the force. The object's velocity will change, either speeding up, slowing down, or changing direction depending on the direction and magnitude of the force.
If the forces are acting on an object are unbalanced what 2 things can happen?
If the forces are unbalanced on an object, it will experience acceleration in the direction of the greater force. This can result in the object either speeding up, slowing down, or changing direction depending on the direction of the forces.
What will happen to an object moving at constant velocity?
An object moving at constant velocity will continue to move in the same direction at the same speed, without changing its velocity or direction unless acted upon by an external force. This is described by Newton's first law of motion.
How does subliming happen?
Sublimation is a change of state when a solid turns into a gas without going in the process of changing into a liquid.
Reflection occurs when a wave does what?
Reflection occurs when a wave encounters a boundary or obstacle and bounces back in the opposite direction. This can happen with various types of waves, including sound waves, light waves, and water waves. Reflection is a fundamental principle in physics and is observed in many natural phenomena.
When a ray of light hits a surface two things will happen to the light. What are they?
When a ray of light hits a surface, two things can happen: reflection, where the light bounces back off the surface, and refraction, where the light enters the material and changes direction.
