Answer:

$41.7975\ ^{\circ}$

Explanation:

$n_2$ = Refraction index of water = 1.333

$n_1$ = Refraction index of air = 1

$\theta_2$ = Angle of sunlight = 30°

From Snell's law we have

$\dfrac{n_1}{n_2}=\dfrac{sin\theta_2}{sin\theta_1}\\\Rightarrow \theta_1=sin^{-1}\dfrac{n_2sin\theta_2}{n_1}\\\Rightarrow \theta_1=sin^{-1}\dfrac{1.333sin30}{1}\\\Rightarrow \theta_1=41.7975\ ^{\circ}$

The angle measured from the vertical does the sunlight strike thesurface of the water is $41.7975\ ^{\circ}$

Which of the following represents an upright image? <br> A. -do<br> B. +m<br> C. -m<br> D. +do

Tom [10]

Answer:

B. +m

Explanation:

The magnification of an image is defined as the ratio between the size of the image and of the object:

$m = \frac{y'}{y}$

where we have

y' = size of the image

y = size of the object

There are two possible situations:

- When m is positive, y' has same sign as y: this means that the image image is upright

- When m is negative, y' has opposite sign to y: this means that the image is upside down

Therefore, the correct option representing an upright image is

B. +m
