Then she asked students to put the slide on a white paper having (X) mark on it.
Students will be able to see the mark clearly (or partially)

A In slide P as it is translucent
B In slide Q as it is translucent
C In slide R as it is opaque
D In all the slides as paint does not change the nature of glass.


It's written'Students will be able to see the mark clearly (or partially)'. What should I do the question is not even making up it's mind!

Ans 1:

Shourya Kumar from Delhi Public School Noida, Noida
Class : Class 7
it is correct r is opaque and we would not be able to see the mark

Ans 3:

Shuvangi Das from Vivekananda mission school, haldia
Class : Class 6
Bcoz when glass Q is painted with light blue we are still able to see the mark , that means its still translucent. When glass R is painted with black, we are not able to see as black is an opaque color. This what the logic meant for. So, option B is correct

Ans 4:

tanmay chaudhry from BAL BHAVAN PUBLIC SCHOOL, New Delhi

Ans 5:

Anika Saha from New Town School, KOLKATA
