Yellow light with wavelength 600 nm is travelling to the left (in the negative x direction) in vacuum. The light is polarized al
kiruha [24]

Answer: (a) and (b) => check attached file.

(c). Picture (a) and (b) will both remain the same.

Explanation:

IMPORTANT: The solution to the question (a) and (b) that is  (a) Draw a neat snapshot mode labeled vector picture of the wave. (b) Draw a neat movie mode labeled vector picture of the wave is there in the ATTACHED FILE/PICTURE.

It is also worthy of note to know that in anything Electromagnetic wave, the magnetic field, the Electric Field and their direction of propagation are perpendicular to each other.

Therefore, knowing the fact above we can say that in yellow light, the magnetic field is in the y-direction and the Electric Field is in the z-direction.

Hence, the solution to option C is given below;

(C).If the wave were to represent blue light instead of yellow light, picture (a) will remain the same because both light are Electromagnetic wave, although the wavelength will have to change. Picture (b) will also remain the same because they are both Electromagnetic waves and possess similar properties.

Which of the following procedures was done to minimize human error? We let the weight swing 25 times and divided by 25 to get th
RUDIKE [14]

Answer:

T = 3.475 s

Time period is independent from mass

Explanation:

- To reduce the human error in taking any measurements we take multiple N number of readings. Then sum up all the readings and divide by N to find an average. The error between each individual reading and the actual reading is reduced by repetition.

- We use the plot of T^2 against L to form a linear relationship between two variables. We square the entire the equation for linearize the equation.

- Given, L = 3 m . The time period is approximated by a pendulum expression given as:

                                     T = 2*pi*sqrt ( L / g )

Where, g is the gravitational acceleration 9.81 m/s^2

- Then we have:

                                     T = 2*pi*sqrt ( 3 / 9.81 )

                                     T = 3.475 s

- From above expression we see that time period is independent from the mass at the end of the string but a function of pendulum geometry and kinetics.
