Planar waves from a monochromatic light source are normally incident on a circular obstacle, which casts a shadow on a screen po

sitioned behind the obstacle. What do the wave properties of light predict about how dark the center of the shadow is?(a) The center of the pattern should be brighter than its surrounding.(b) The center of the pattern should be darker than its surrounding.

Answer:

correct  is the A

Explanation:

The light is a wave that has travels from two different places, each side of the circular obstacle, so an interference process must be given, which is described by the expression

                a sin θ  = m λ

Where a is the size of the slit, λ the wavelength and m an integer that indicates the order of diffraction.

In the case of the central point, the difference in the optical path of each ray stop is zero, which implies that in some it is also zero, so the waves are in phase for this point and a bright spot must be seen in the center.

When reviewing the answer the correct one is the A

Gravitational force is determined by which of the following
hram777 [196]

Gravitational force is determined by mass

Answer: Option B

<u>Explanation:</u>

According to Universal law of gravity, the gravitational force is directly proportional to the product of the masses of the objects and inversely proportional to the square of the distance between the objects.

            F=G \times \frac{m_{1} \times m_{2}}{r^{2}}

Where,

G – gravitational constant = \text { 6. } 67 \times 10^{-11} \mathrm{Nm}^{2} / \mathrm{kg}^{2}

\boldsymbol{m}_{1}, \boldsymbol{m}_{2} = masses of two objects

r – distance between the objects

So, as per this law, the gravitational force is found by mass.

as the trait is dominant and controlled by a single gene,the mutation must have occurred on both diploid copies. true or false?
GenaCL600 [577]

Answer:

False

Explanation:

A dominant trait is a trait that is inherited from parents. It is a trait that is obtained from a particular copy or type of a gene that overshadows or overwhelms the effects of another type or copy of that gene. Dominant traits are controlled by a single gene.

Therefore , as the trait is dominant and controlled by a single gene,the mutation must have occurred on both diploid copies is a false statement.

How do the amplitudes of a 120 decibel sound and a 100-decibel sound compare?​
NemiM [27]
The 120 decibel sound has more amplitude than the 100 decibel sound.

In Physics, the relation between amplitude and intensity is that the intensity of the wave is directly proportional to the square of its amplitude.
