An incident ray strikes a piece of diamond at an angle of 40.5 degrees. The index of refraction of air is 1.0003 and the index o
horrorfan [7]

The angle of refraction is 15.6 deg.

When a ray of light passes from medium 1 to medium 2, the refractive index of medium 2 with respect to 1 is the ratio of the absolute refractive index of medium 2 and medium 1

_1n_2 =\frac{n_2}{n_1}

When light passes from air into diamond, with the given values of refractive indices,

_an_d =\frac{n_d}{n_a}  =\frac{2.42}{1.0003} =2.4193

According to Snell's law,

_an_d=\frac{sini}{sinr} \\  sinr=\frac{sini}{_an_d} =\frac{sin(40.5)}{2.4193}=0.2684\\   r=arcsin(0.2684)=15.57 deg

The angle of refraction is 15.6 deg

What direct current in A will produce the same amount of thermal energy, in a particular resistor, as an alternating current tha
vodomira [7]

Answer:

I_{rms}= 4.314 AExplanation:According to the definition of the root mean square value of current, the value of direct current which passes through the same circuit in which an alternating current is passing and producing same amount of heat as the direct current produced is called root mean square value of current. So, the relation between the root mean square value of current and the peak value of alternating current is given by [tex]I_{rms}=\frac{I_{0}}{\sqrt{2}}

I_{rms}=\frac{6.1}}{\sqrt{2}}

[tex]I_{rms}= 4.314 A
