Chemistry

• What happens to waves when they encounter a barrier or pass through a gap?


  They spread out and change direction.
• When is diffraction more pronounced?


  When the wavelength is similar to the size of the obstacle or opening.
• What does diffraction demonstrate about waves?


  It demonstrates waves' ability to spread beyond direct linear paths.
• What are the two main factors that affect diffraction?


  The wavelength of the wave and the size of the opening or obstacle.
• When is diffraction most noticeable?


  When the wavelength is similar to the size of the opening or obstacle.
• How does diffraction occur through wave interference?


  Waves spread out, bend at different angles, and create interference patterns.
• How do intermolecular forces differ from chemical bonds?


  They act between different molecules, not within
• How do dipole-dipole forces work?


  Molecules attract like tiny magnets due to charge separation
• What is required for hydrogen bonds to form?


  Hydrogen bonded to highly electronegative atoms
