REFLECTION
Why is reflection important in our lives?
Reflection is important because it helps us learn from our experiences, understand our mistakes, and improve our decisions in the future.
What is refraction?
Refraction is the bending of light when it passes from one medium to another, like from air to water.
What is total internal reflection?
Total internal reflection is when light traveling in a denser medium reflects completely back into the medium instead of passing into the less dense medium.
What is a lens?
A lens is a transparent object that bends (refracts) light to form an image.
How can reflecting on mistakes help us grow?
Reflecting on mistakes allows us to see what went wrong and avoid repeating the same errors. It helps us become more responsible and mature.
Why does refraction happen?
Refraction happens because light changes speed when it enters a different medium.
When does total internal reflection occur?
It occurs when light moves from a denser medium to a less dense medium and the angle of incidence is greater than the critical angle.
What are the two main types of lenses?
The two main types are convex (converging) lenses and concave (diverging) lenses.
What can we learn about ourselves through reflection?
Through reflection, we can discover our strengths, weaknesses, values, and goals. It helps us understand who we really are.
What happens to light when it goes from air into water?
When light goes from air into water, it slows down and bends toward the normal.
. What is the critical angle?
The critical angle is the minimum angle of incidence at which light is completely reflected inside the medium.
What does a convex lens do to light?
A convex lens brings parallel light rays together to a focal point.
How does reflection improve decision-making?
Reflection improves decision-making because it helps us think carefully about consequences before acting.
Can you give an example of refraction in daily life?
Yes. A spoon looks bent when placed in a glass of water because of refraction.
What is an example of total internal reflection in real life?
Optical fibers use total internal reflection to transmit light signals over long distances.
Give one use of lenses in real life.
Lenses are used in glasses, microscopes, cameras, and telescopes to help form clear images.
When is a good time to reflect?
A good time to reflect is after an important event, at the end of the day, or when making an important decision.
What is the normal line in refraction?
The normal is an imaginary line drawn perpendicular (90°) to the surface where the light hits
Why doesn’t light refract during total internal reflection?
Because the angle of incidence is larger than the critical angle, so all the light is reflected and none passes through.
What does a concave lens do to light?
A concave lens spreads parallel light rays apart.
