Q. A bar chart shows the number of books read by four students: John, Mary, Alex, and Sarah. If John read 15 books, Mary read 20 books, Alex read 10 books, and Sarah read 25 books, who read the most books? (2023)
Q. A bar chart shows the number of hours spent on different activities. If the hours for activity A is 8, B is 6, C is 4, and D is 10, which activity took the least time? (2023)
Q. A bar graph illustrates the number of customers visiting a store over four weeks. If Week 1 had 120 customers, Week 2 had 150, Week 3 had 180, and Week 4 had 200, what is the average number of customers per week?
Q. A bar graph shows the sales of a product over four quarters: Q1: 150, Q2: 200, Q3: 250, Q4: 300. What is the percentage increase in sales from Q1 to Q4?
A.
100%
B.
150%
C.
200%
D.
250%
Solution
The increase in sales from Q1 (150) to Q4 (300) is 300 - 150 = 150. The percentage increase is (150/150) * 100% = 100%.
Q. A beam of light enters a prism with an angle of 60 degrees. If the refractive index of the prism is 1.5, what is the angle of refraction inside the prism?
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
90 degrees
Solution
Using Snell's law, sin(θ2) = sin(60)/1.5, we find θ2 = 30 degrees.
Q. A beam of light enters a prism with an angle of incidence of 45 degrees. If the refractive index of the prism is 1.5, what is the angle of refraction inside the prism?
Q. A beam of light in glass (n=1.5) strikes the glass-air interface at an angle of 60°. Will total internal reflection occur?
A.
Yes
B.
No
C.
Only if the angle is increased
D.
Only if the angle is decreased
Solution
To determine if total internal reflection occurs, we first find the critical angle using sin(θc) = 1/n = 1/1.5, which gives θc ≈ 41.8°. Since 60° > 41.8°, total internal reflection will not occur.
Q. A beam of light passes from air into a medium with a refractive index of 1.5. If the angle of incidence is 30 degrees, what is the angle of refraction? (2022)
Q. A beam of light passes through a narrow slit and produces a diffraction pattern. What happens to the width of the central maximum if the slit width is decreased? (2019)
A.
It increases
B.
It decreases
C.
It remains the same
D.
It becomes zero
Solution
According to the diffraction principle, as the slit width decreases, the width of the central maximum increases.
Q. A beam of light passes through a prism with a refractive index of 1.5. If the angle of the prism is 60 degrees, what is the angle of minimum deviation?
A.
30 degrees
B.
45 degrees
C.
60 degrees
D.
75 degrees
Solution
For a prism, the angle of minimum deviation D is given by D = A(n - 1), where A is the angle of the prism. Here, D = 60(1.5 - 1) = 30 degrees.
Q. A beam of light passes through a prism with an angle of 60 degrees. If the refractive index of the prism is 1.5, what is the angle of deviation? (2023)
A.
30 degrees
B.
60 degrees
C.
45 degrees
D.
15 degrees
Solution
Using the formula for angle of deviation: D = A(n-1), we find D = 60(1.5-1) = 30 degrees.
Q. A beam of light passes through a thin convex lens with a focal length of 15 cm. If the object is placed 30 cm from the lens, what is the image distance?
A.
10 cm
B.
15 cm
C.
20 cm
D.
30 cm
Solution
Using the lens formula, 1/f = 1/v - 1/u; here, f = 15 cm and u = -30 cm. Thus, 1/v = 1/15 + 1/30 = 1/10, giving v = 10 cm.
