10.00cm
6.00cm
5.00cm
1.50cm
Correct answer is B
\(\frac{1}{u} + \frac{1}{v} = \frac{1}{f} = \frac{1}{15} + \frac{1}{10}\)
u = 6.00
68o
56o
34o
18o
Correct answer is C
c = \(\sin^{-1} \frac{1}{n} = \sin^{-1} \frac{1}{1.8} = 34^o\)

4.50 x 1010Hz
5.0 x 109Hz
4.5 x 109Hz
2.0 x 106Hz
Correct answer is D
f = \(\frac{V}{\lambda} = \frac{3 \times 10^8}{150}\)
= 2.0 x 10\(^6\) Hz
