Focus on Light and Soundwaves

Front

What is the reflective property of light?

Back

The reflective property of light refers to the ability of light rays to bounce back when they hit a surface, such as a mirror.

Front

What tool can be used to demonstrate the reflective property of light?

Back

A mirror is commonly used to demonstrate the reflective property of light.

Front

What happens to light rays when they are reflected?

Back

When light rays are reflected, they bounce back from the surface they hit.

Front

What is absorption in the context of sound waves?

Back

Absorption is the process by which materials, like carpet and draperies, hold the energy of sound waves, reducing the loudness of sounds.

Front

What type of lens is used to correct nearsightedness?

Back

A concave lens is used to correct nearsightedness by spreading light rays before they reach the eye.

Front

What is the difference between reflection and refraction of light?

Back

Reflection is when light bounces back from a surface, while refraction is the bending of light as it passes from one medium to another.

Front

What is a convex lens?

Back

A convex lens is a lens that is thicker in the center than at the edges and converges light rays to a focal point.

Front

What is a plane mirror?

Back

A plane mirror is a flat mirror that reflects light to form an image that is the same size as the object.

Front

What is the role of a prism in light behavior?

Back

A prism can refract light, separating it into its component colors, creating a spectrum.

Front

What is the definition of sound wave absorption?

Back

Sound wave absorption is the process where materials take in sound energy, reducing the intensity of sound.
