Wave Behaviour

The video tutorial explores the behavior of light and sound waves, discussing their types, such as transverse and longitudinal. It covers wave behaviors like reflection, transmission, refraction, diffraction, absorption, and scattering. Reflection involves waves bouncing off surfaces, while transmission sees them passing through objects. Refraction occurs when waves change speed across different mediums, altering direction. Diffraction involves waves spreading through gaps, and scattering explains phenomena like the blue sky. The tutorial also explains how light interacts with objects, affecting color perception based on absorption and reflection of wavelengths.

What are the two main types of waves?

• Transverse and Longitudinal

• Visible and Invisible

• Sound and Light

• Electromagnetic and Mechanical

Why do we hear echoes?

• Because sound waves are scattered in all directions

• Because sound waves are transmitted through walls

• Because sound waves are reflected by hard surfaces

• Because sound waves are absorbed by soft surfaces

What happens to light when it passes through a window?

• It is reflected back

• It is absorbed completely

• It scatters in all directions

• It continues to travel in the same direction

Why does a straw appear bent in a glass of water?

• Because of diffraction

• Because of reflection

• Because of scattering

• Because of refraction

What causes the sky to appear blue?

• Absorption of red light

• Diffraction of light through clouds

• Scattering of shorter blue wavelengths

• Reflection of sunlight
