According to the law of reflection, the angle of incidence is equal to the angle

Question

According to the law of reflection, the angle of incidence is equal to the angle of reflection greater than the angle of reflection lest than the angle of reflection. At a quiet pond with crystal clear water, you decide to practice fishing with a bow and arrow but you do NOT want to hit a fish, if you want to miss the fish, you must aim directly at the fish you see. farther down from the surface than you perceive the fish to be A vertically polarized beam of light of intensity 100 W/m^2 passes through a polarizer with its polarizing axis at 60 degrees with the vertical. What is the intensity of the transmitted light? 50 W/m^2 25 W/m^2 12.5 W/m^2. Which of these waves has the largest frequency ? radio waves infrared waves X-Rays ultraviolet waves light waves Which of these waves has the shortest wavelength? light waves radio waves x-rays gamma rays The ratio of the electric field magnitude to the magnetic field magnitude in a plane electromagnetic wave is the speed of light c. True False Two electromagnetic waves are traveling in a vacuum. The wave with the larger wavelength has a higher frequency that the other wave has a lower frequency that the other wave has a larger speed than the other wave has a smaller speed than the other wave Using the right-hand rule, the direction of propagation of a plane electromagnetic wave is given by your right index finger right thumb. True or False. A convex mirror always produces a virtual image with magnification of magnitude less than one. True False True or False. A concave mirror always produces a real image of an object placed in front, True False The focal length of a converging thin lens is f = 5.0 cm. If an object is placed 10 cm in front of the lens, then the real image will have what distance d behind the lens? d_i = 5.0 cm d_i = -10 cm d_i = 10 cm none of the above The focal length of a concave mirror is f = 10.0 cm. If an object is placed 20 cm in front of the mirror, then the real image will have what distance d_i in front of the mirror? d_i = 10 cm d_i = 20 cm d_i = 5 cm none of the above

Explanation / Answer

( 1 )

According to law of reflection, the angle of incidence is equal to angle of reflection.

Correct option is ( a )

( 2 )

If you want the miss the fish, you must aim farther down from the surface. Because, due to refraction of light it appear at the bottom to the actual postion. The fish is deeper than it appears. If you air this location, you should miss your aim

Correct option is ( b )

( 3 )

In accordance with Malus's law

I = Io cos2 ( 60 ) = 100 cos2 ( 60 ) = 25 W/m^2

Correct option is ( b )

( 4 )

THe frequency increases in the order, radio waves, micro, infrared, visible, Uv, X ray , and gamma ray

Thus,the correct option is ( c )

( 5 ) Shorter wavelength corresponds to longer frequency, gamma rays

Correct option is ( d )
