Given an ideal Young’s double slit (i.e. the slit width is infinitely small and can therefore be neglected) onto which a plane wave with a wavelength of \lambda = 400 nm impinges. The distance between the two slits d is 1,2 mm. At a distance a = 15 dm behind the double slit there is a screen on which a corresponding interference pattern can be observed. (i) Calculate the distance x between the 1st secondary maximum and the main maximum of the interference pattern (Note: Since d«a applies here, you can use the following approximation: tan(\phi ) ≈ sin(\phi )). (ii) What is the frequency range in which the electromagnetic wave considered here is located? (iii) How does the distance between the maxima of the interference pattern change when infrared radiation hits the double slit? (iv) Sketch qualitatively the interference pattern of the ideal double slit, the single slit and the real double slit

Q.1) (a) Solve the equation $2\sin^2\theta - \sin\theta = 0$ exactly for $\theta \in [0, 2\pi]$. (b) Let $\alpha$ be an angle in the first quadrant such that $\sin\alpha = 3/4$. Find the exact values of $\cos\alpha$, $\sin 2\alpha$, and $\tan\alpha$.

4. The block shown right is made of gluing two bocks together along a slanted plane. For the given stress shown, find the normal and shear stress along the glued interface. Use the transformation equations in Prob. ( understanding the concept of transformation and the equations; Understand the meaning of $\theta$ in the equations is the most important) 5.

This program should be in JavaScript. Question 3 (20 points Saved) Write a program that plays the "Guess the Number" game with the user. The game rules and steps are as follows: 1. The program first asks the user to think of a number in the range [1, 100]. 2. The program then asks the user to confirm if they are ready to start the game. If the user does not confirm, the program goes to Step 1. Otherwise, the program goes to Step 3. 3. The program initializes two variables, namely "low" and "high", with the values of 1 and 100, respectively. 4. The program calculates the guessed number, gas: low + high / 2, if low + high is even. Otherwise, it calculates low + high - 1 / 2. 5. The program shows the guessed number to the user and asks the user to enter one of the following values with the specified meanings, and flows to Step 6: - Showing that the guessed number is greater than the number that the user picked. - Showing that the guessed number is less than the number that the user picked. - Showing that the guessed number is equal to the number that the user picked. - Otherwise, if the user enters "g", the program sets low to g1 and goes to Step 4. - Otherwise, if the user enters "t", the program terminates. - If the user enters any other character, the program displays an error message and goes to Step 5. As the above steps show, once the game starts, it will continue until the program can guess the number that the user picked.
