If the separation between the openings in a laser is increased, then the distance between the interference fringes decreases
<h3>What is Interference fringe ?</h3>
Interference fringe refers to bands caused by different lights which can be found in phase or not each other.
- Distances between laser fringes are short which is due to light wavelength.
- The interference fringes can be estimated by knowing slit separation and wavelength.
In conclusion, if the separation between the openings in a laser is increased, then the distance between the interference fringe decreases

9*
m
Explanation:
Step 1:
We are given the initial length of the Pyrex glass dish at a particular temperature and need to calculate the change in the length when the temperature changes by 120° C. The coefficient of linear expansion of Pyrex is provided.
Step 2:
Change in length = Coefficient of linear expansion * Change in temperature * Initial length
Step 3:
Coefficient of linear expansion = 3*
/°C
Change in temperature = 120°C = 120 K
Initial length = 0.25 m
Step 4:
Change in length = 3* * 120 * 0.25 = 9* m
Magnitude of displacement = 
Adding the squares gives displacement = 
Displacement = ≈ 724.7m
Answer:
1.67 m/s
Explanation:
Momentum is conserved.
Initial momentum = final momentum
(30 kg) (10 m/s) + (35 kg) (-10 m/s) = (30 kg) v + (35 kg) (0 m/s)
300 - 350 = 30v
v = -5/3 m/s
Linus will move at 1.67 m/s in the direction opposite that he started.
