Answer:
The distance between interference fringes increases.
Explanation:
In a double-slit diffraction pattern, the angular position of the nth-maximum in the diffraction patter (measured with respect to the central maximum) is given by

where
is the angular position
is the wavelength
d is the separation between the slits
In this problem, the separation between the slits decreases: this means that d in the formula decreases. As we see, the value of
(and so, also
) is inversely proportional to d: so, if the d decreases, then the angular separation between the fringes increases.
So, the correct answer is
The distance between interference fringes increases.
I'd say that because of gravity and the material made the red giant it's holding all the material together to be in one piece years and years to come.
Hope that helped! <3 ^-^
Yes, it is because gravity is a force of attraction to the center of our planet, Earth. If we drop a pencil, the pencil will go on the floor. Gravity is pulling the pencil down.
The wavelength was doubled, and its energy will be increased by 4 times.
looking at the formula
energy 
also, 
hence it is clear from above that energy is directly proportional to the square of the wavelength.
hence, The wavelength was doubled, and its energy will be increased by 4 times.
<h3>
What is Wavelength?</h3>
- The distance over which a periodic wave's shape repeats is known as the wavelength in physics.
- It is a property of both traveling waves and standing waves as well as other spatial wave patterns. It is the distance between two successive corresponding locations of the same phase on the wave, such as two nearby crests, troughs, or zero crossings.
- The spatial frequency is the reciprocal of the wavelength. The Greek letter lambda is frequently used to represent wavelength.
- The term wavelength is occasionally used to describe modulated waves, their sinusoidal envelopes, or waves created by the interference of several sinusoids.
