Answer:

4.  D and E

Explanation:

As we know that the relation between phase difference and path difference is given below

\delta \phi = \frac{2\pi}{\lambda} \delta x

now we have to find the distance of two points which are out of phase by 90 degree

so here we will have

\frac{\pi}{2} = \frac{2\pi}{\lambda} \delta x

so from above we have

\delta x = \frac{\lambda}{4}

so the distance between the points will be 1/4 times of wavelength

so here correct answer is

4. D and E

Bob is threatening Tom’s life with a giant laser with wavelength (650 nm), a distance (D = 10 m) from the wall James is shackled
Fittoniya [83]

Answer:

He should stand from the center of laser pointed on the wall at 1.3 m.

Explanation:

Given that,

Wave length = 650 nm

Distance =10 m

Double slit separation d = 5 μm

We need to find the position of fringe

Using formula of distance

d\sin\theta=n\lambda

d\dfrac{y}{D}=n\lambda

y=\dfrac{\lambda D}{d}

Put the value into the formula

y=\dfrac{650\times10^{-9}\times10}{5\times10^{-6}}

y=1.3\ m

Hence, He should stand from the center of laser pointed on the wall at 1.3 m.

Leokris [45]

Answer:

The answer is B

Explanation:

250g = 0.25kg

F = m × a

a = F/m

= 1.2/0.25

= 4.8m/s²
