Answer:
Diffraction patterns are due to INTERFERENCE.
Explanation:
the first order bright band
A= 0.78
B= 0.11
C= 0.032
D= 0.62
The angle between the central bright band and the first order bright band is 0.78⁰, hence option A is correct.
According to the question:
A light with a wavelength of 410 nm falls on two slits separated by 0.03 mm,
So, the angle between the central bright band and the first order bright band is,
The angle will be, θ = λ/d radian
λ = 410 nm (410 × 10 ⁻⁹ m)
d = separation of slits (0.03 mm) or 0.03 × 10 ⁻³ m
θ =
= 0.01367 radian
= 0.01367 × (180/π)⁰
= 0.78⁰
Thus, the angle between the central bright band and the first order bright band is 0.78⁰, hence option A is correct.

B
Explanation:
The time for the ball to reach the bottom of the ramp is 5 seconds. Using this time value, the acceleration, and the initial velocity, you can calculate the length of the ramp, which is found to be 125 cm.
The question involves the physics principles of kinematics, specifically the concept of acceleration. Given that the initial velocity is 0 cm/s, the final velocity is 50 cm/s, and the acceleration is 10 cm/s^2, you can find the time it took for the ball to reach the bottom using the formula vf=vi+at (Final velocity = initial velocity + acceleration * time). Substituting the given values, you get the equation 50cm/s = 0cm/s + 10cm/s^2 * time, simplifying which gives time = 5 seconds.
To find the length of the ramp, you can use another kinematic equation, d = vit + 0.5at^2 (Distance = initial velocity * time + 0.5 * acceleration * time^2). Substituting the values we know, (initial velocity = 0, acceleration = 10 cm/s^2, time = 5 s), the equation simplifies to d = 0*5 + 0.5*10*5^2 = 0 + 0.5*10*25 = 125 cm. Therefore, the length of the incline or ramp is 125 cm.
