## Study Notes

Reflection, Refraction, and Diffraction of Waves

• Waves undergo specific behaviors when they encounter the end of a medium, including reflection and transmission.
• Two-dimensional waves, such as water waves, can be studied using a ripple tank to observe reflection, refraction, and diffraction.
• A linear object in water can become a source of straight waves with alternating crests and troughs.
• When straight waves encounter an obstacle, they bounce off and change direction according to the law of reflection.
• Waves reflecting off a parabolic surface converge at a focal point and spread out again.
• Refraction involves a change in direction, speed, and wavelength of waves passing from one medium to another.
• Water waves travel fastest in deep water and slow down and bend when passing from deep to shallow water.
• Refraction is observed in a ripple tank partitioned into deep and shallow sections.
• Diffraction is the bending of waves around obstacles and openings and is observed in water waves, sound waves, and light waves.
• The amount of diffraction increases with increasing wavelength.
• Diffraction of sound waves is commonly observed and used by forest-dwelling birds such as owls to communicate across long distances.
• Diffraction of light waves is only observed when encountering obstacles with extremely small wavelengths.

Test your knowledge on the fascinating behaviors of waves in this quiz on reflection, refraction, and diffraction. Explore the concepts of how waves interact with the end of a medium, and how they can change direction, speed, and wavelength when passing from one medium to another. Discover the properties of straight waves and how they react to obstacles, as well as the bending of waves around obstacles and openings. From water waves to sound and light waves, this quiz will broaden your understanding of the fascinating world of
