borishaifa [10]

Answer:

The power of the mirror is -17.24 diopter.

Explanation:

Magnification of an image,m = \frac{1}{6}

Distance of the object from the mirror = u = 29.0 cm

Distance of an image from the mirror = v

Magnification = m=\frac{-v}{u}

\frac{1}{6}=\frac{-v}{u}

v=\frac{-u}{6}

\frac{1}{f}=\frac{1}{u}+\frac{1}{v}

\frac{1}{f}=\frac{1}{u}+\frac{-6}{u}

f=\frac{-u}{5}=\frac{-29.0 cm}{5}=-5.8 cm

Focal length of mirror = -5.8 cm =-0.058 m

Power of the lens = P

P =\frac{1}{f}

P=\frac{1}{-0.058 m}=-17.24 D

fgiga [73]

Answer:

θr = 55.2 °

Explanation:

The law of reflection states that the angle of incidence and the angles of reflection is the same.

Let's use trigonometry to find the angle between the reflected ray, where the horizontal distance x = 55.9 cm and the vertical distance is y = 38.9 cm

    tan θ = y / x

    tan θ = 38.9 / 55.9

    θ = tan⁻¹ (0.6959)

    θ = 34.8°

This angle is measured with respect to the x-axis (horizontal), but in general the angles in optics are measured from the y-axis so that the angle is

    θ = 90 - 34.8

    θr = 55.2 °
