Reflection and Refraction of light

What can you infer about the refractive index of Medium A and Medium B?

• Medium A has higher Refractive Index than Medium B

• Medium A has lower Refractive Index than Medium B

• Medium A has the same Refractive Index as Medium B

Which of the following is NOT a characteristic of the image of a plane mirror?

• It is laterally Inverted

• It is real

• It is upright

• It has the same distance from the mirror as the object.

The path of a ray of light coming from air into a rectangular glass block was traced by four students. Which student drew the light ray diagram correctly?

• Student A

• Student B

• Student C

• Student D

According to the second Law of Reflection, angle of incidence is equal to angle of ________________.

• Reflection

• Refraction

• Incidence

• Inflection

What is the angle of incidence for a light having zero angle of reflection?

• Not Possible

• 0 degrees

• 45 degrees

• 90 degrees

What happens to light when it travels from an optically less dense medium to an optically denser medium?

• Increase in velocity

• Decrease in velocity

• decrease in wavelength

• Both decrease in velocity and wavelength

Why is the refractive index of a transparent medium other than vacuum ALWAYS greater than 1?

• Speed of light in vacuum is greater than speed of light in transparent medium

• Speed of light in vacuum is less than speed of light in transparent medium

• frequency of light changes when it travels from transparent medium to vacuum.

You are given three mediums A, B and C. Their refractive index are 1.33, 1.45 and 1.5 respectively. Which medium will light travel the fastest in?

• 1.33

• 1.45

• 1.5

• It will all travel the same speed

When light falls onto a smooth, polished surface, most of it is:

• reflected in the same direction

• reflected in different directions

• scattered

• refracted to another medium

Magnification = Size of image/ Size of Object. What is the magnification of a plane mirror?

• 0.5

• 1

• 2

• 10
