Q. What is the angle of diffraction for the first minimum in a single-slit diffraction pattern if the slit width is 0.5 mm and the wavelength of light is 500 nm? (2023)
A.
30°
B.
60°
C.
45°
D.
15°
Solution
The angle for the first minimum is given by sin θ = λ/a, where a is the slit width. Thus, sin θ = 500 nm / 0.5 mm = 0.001, leading to θ ≈ 30°.
Q. What is the basic unit of classification in biology? (2020)
A.
Species
B.
Genus
C.
Family
D.
Order
Solution
The basic unit of classification in biology is the species, which is defined as a group of organisms that can interbreed and produce fertile offspring.
Q. What is the boiling point elevation for a solution with 0.5 moles of a non-volatile solute in 1 kg of water? (Kb for water = 0.512 °C kg/mol) (2022)
A.
0.256 °C
B.
0.512 °C
C.
1.024 °C
D.
0.128 °C
Solution
Boiling point elevation (ΔTb) = Kb * m = 0.512 °C kg/mol * 0.5 mol/kg = 0.256 °C.
