Reflection in Physics

What is the primary definition of reflection in physics?

• The change in direction of waves due to gravity.

• The phenomenon of light passing through transparent materials.

• The way light, sound, and other waves bounce off surfaces.

• The process of light being absorbed by a surface.

Which of the following is NOT a type of reflection?

• Specular reflection

• Diffuse reflection

• Absorptive reflection

• Both specular and diffuse reflection

Which of the following best describes specular reflection?

• Reflection from a rough surface that scatters light.

• Reflection from a smooth, shiny surface like a mirror.

• Reflection that occurs only in water bodies.

• Reflection that absorbs all incoming light.

What type of surface is most likely to produce specular reflection?

• A frosted glass window.

• A rough, textured wall.

• A calm body of water.

• A crumpled piece of paper.

What is the law of reflection?

• The angle of incidence is always greater than the angle of reflection.

• The angle of reflection is always zero.

• The angle of incidence is equal to the angle of reflection.

• The angle of incidence is equal to the angle of refraction.

Which scenario best illustrates diffuse reflection?

• Light reflecting off a calm lake.

• Light bouncing off a rough wall.

• Light reflecting off a polished car surface.

• Light passing through a clear window.

How do mirrors utilize the principle of reflection?

• They reflect light in a predictable manner.

• They refract light to distort images.

• They absorb light to create images.

• They scatter light in multiple directions.

What happens to sound waves when they encounter a hard surface?

• They bounce back, creating echoes.

• They pass through without any change.

• They disappear entirely.

• They are completely absorbed.

Why are telescopes and microscopes dependent on reflection?

• They use lenses to magnify images.

• They rely on mirrors to gather and focus light.

• They operate without any light at all.

• They absorb light to enhance visibility.

In what way is the behavior of a bouncing ball similar to light reflection?

• The angle at which the ball hits the wall is equal to the angle at which it bounces back.

• The ball changes color upon bouncing.

• The ball absorbs energy from the wall.

• The ball travels in a straight line without changing direction.
