A ray of white light enters the raindrop and undergoes __________ and __________ to form a spectrum.

• refraction; dispersion

• reflection; dispersion

• dispersion; diffraction

• scattering; dispersion

The splitting of white light into the seven colors when it passes through a transparent material is called

• Refractrion

• Dispersion

• Reflection

• Diffraction

Sunlight is white, it contains all the colors of the ________.

When white light passes through a prism,

• red bends more, violet bends least

• red bends least, violet bends most

• dispersion doesn't occur

• refraction doesn't occur

 $\angle D$  is called as

• Angle of incidence

• Angle of deviation

• Angle of dispersion

• Angle of refraction

The perpendicular line drawn from the surface of any surface is called as

• Normal

• Incident Ray

• Refracted ray

• Emergent ray

When white light passes through a prism,

• red bends more, violet bends least

• red bends least, violet bends most

• dispersion doesn't occur

• refraction doesn't occur

The splitting of white light into the seven colors when it passes through a transparent material is called

• Refractrion

• Dispersion

• Reflection

• Diffraction

Red light has

• longer wavelength

• shorter wavelength

• longer frequency

• none of the above

When white light enters a prism, it gets split into its constituent colours. This is due to

• different refractive index for different wavelength of each colour

• each colours has same velocity in the prism.

• prism material have high density.

• Scattering of light
