What is being blocked when a shadow is formed?

• Light Source
• Light Path
• Object
• Eye

Why is the component of color in a rainbow can be seen when light passes through a glass prism?

• phenomena of scattering of light

• phenomena of dispersion of light

• phenomena of reflection of light

• phenomena of diffraction of light

Why is the spectrum of light separated into its components of color when white light is directed to a prism?

• Because light reflects off the prism's surface

• The incident white light refracts and separates into its constituent colors

• The white light is absorbed by the prism, separating its colors

• The light speeds up as it moves from air into the denser plastic material

Look at the diagram given. This is the first prism. What happen if A SECOND inverted prism is placed behind the first prism?

• the various colors pass through it and form brighter spectrum

• the various colors pass through it and form a white light back

• the various colors pass through it and form an opposite spectrum colors

• nothing will happen

This is the example of dispersion of light

• sky looks bright orange in the evening

• shadow

• Pool seems shallower

• rainbow

these are examples of phenomenon of scattering of light except

• Sky appears blue at midday

• Sky appears reddish in the evening

• Rainbow after rain

Why does scattering of light occur?

• Light rays are reflected by atmospheric molecules and scatter in all directions

• Light rays are blocked and refracted to all directions by the clouds or particles in the air

• Light rays are transmitted and refracted in all directions by the clouds or particles in the air

What is the difference between reflection and refraction? 

• Both involve light bending through a medium
• Reflection is light bouncing off a medium's surface and refraction is light bending through a medium
• Reflection is light bending through a medium's surface and refraction is light bouncing off a medium
• Refraction is light being absorbed in a medium and reflection is light being bent through a different medium
