Wave Interactions

Front

What is diffraction?

Back

Diffraction is the bending of waves around obstacles and openings. It occurs when a wave encounters an edge or a slit, causing it to spread out.

Front

How does the size of an opening affect diffraction?

Back

As the size of the opening increases, the diffraction effects decrease. This means that waves passing through larger openings spread out less.

Front

What is reflection in terms of wave interactions?

Back

Reflection is the bouncing back of a wave when it hits a surface that does not absorb the wave's energy.

Front

What are the types of reflection of light?

Back

The types of reflection of light include diffused reflection, regular reflection, and multiple reflection.

Front

What is constructive interference?

Back

Constructive interference occurs when two or more waves meet and combine to form a wave with a larger amplitude.

Front

What is destructive interference?

Back

Destructive interference occurs when two or more waves meet and combine to form a wave with a smaller amplitude or cancel each other out.

Front

What is refraction?

Back

Refraction is the bending of waves as they pass from one medium to another, caused by a change in speed.

Front

What is absorption in wave interactions?

Back

Absorption is the process by which a wave's energy is taken in by a material, converting it to other forms of energy, such as heat.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.

Front

What is the difference between regular and diffused reflection?

Back

Regular reflection occurs on smooth surfaces, producing clear images, while diffused reflection occurs on rough surfaces, scattering light in many directions.
