Understanding Wave Behavior

What are the two main types of waves?

• Diffusive and scattering

• Absorptive and transmissive

• Reflective and refractive

• Transverse and longitudinal

Why do we hear echoes?

• Due to wave transmission

• Due to wave absorption

• Because of wave diffraction

• Because sound waves are reflected

What effect does a smooth surface have on light waves?

• It refracts them

• It reflects them regularly

• It absorbs them

• It scatters them

What happens when light waves pass through a window?

• They are diffracted

• They are transmitted

• They are reflected

• They are absorbed

What determines the color of an object?

• The color it transmits

• The color it absorbs

• The color it reflects

• The color it diffracts

Why do white objects appear white?

• They absorb all colors

• They reflect all colors

• They scatter all colors

• They transmit all colors

How can noise be reduced in a room?

• By painting the walls white

• By increasing the room's temperature

• By using objects that absorb sound

• By adding more light sources

How can the noise level be reduced from upstairs neighbors?

• By using reflective materials

• By carpeting floors and using curtains

• By using thicker walls

• By installing more windows

What causes refraction?

• Change in wave speed due to different densities

• Reflection off smooth surfaces

• Absorption by opaque materials

• Scattering by particles

What causes a straw in water to appear bent?

• Scattering

• Diffraction

• Refraction

• Reflection
