Answer:

Both are at the side of the spectrum that has the lowest frequency.

Explanation:

We know that the electromagnetic spectrum is the set of several waves that are arranged in order of increasing wavelength of decreasing frequency. It consists of many waves like,

gamma rays, x- rays, ultraviolet rays, visible, infrared rays, microwave, radio waves.

Radio wave has the longest wavelength while gamma rays has maximum wavelength. From the attached figure, it is clear that the frequency of radio wave is least and that of microwave is second least frequency.

Hence, the correct option is (c).

If the opening to the harbor acts just like a single-slit which diffracts the ocean waves entering it, what is the largest angle
soldi70 [24.7K]

Answer:

The angle that the wave would be \theta = sin ^{-1}\frac{2 \lambda}{D}

Explanation:

From the question we are told that  the  opening to  the  harbor acts just like a single-slit so a boat in the harbor that at angle equal to the second diffraction minimum would be safe and the  on at angle greater than the diffraction first minimum would be slightly affected

  The minimum is as a result of destructive interference

       And for single-slit this is mathematically represented as

               D sin \ \theta =m \lambda

where D is the slit with

          \theta is the angle relative to the original direction of the wave

         m is the order of the minimum j

        \lambda is the wavelength

Now since in the question we are told to obtain the largest angle at which the boat would be safe

      And the both is safe at the angle equal to the second minimum then

    The the angle is evaluated as

           \theta = sin ^{-1}[\frac{m\lambda}{D} ]

Since for second minimum m= 2

The  equation becomes

               \theta = \frac{2 \lambda}{D}
