Explanation- k’_max= 2k_max

K’_max= hc/ $\lambda -?$

2K_max= hc/ ${\lambda }^{\text{'}}-{?}_0$

2 (1230/600- $?$ )= (1230/400- $?$ )

So $?$ =1.02eV

A career in the Aviation industry is such that students would not have fixed work hours/shifts. While the first profession that comes to mind when thinking of a career in the Aviation industry is that of a Pilot it is worth knowing that there are other career profiles that candidates can pursue in this field. Students can check the list of career options available after completing BBA in Airport Aviation Management from Tritya Air Hostess Academy:

Explanation- during photoelectric emission the momentum is transferred to metal. metal absorbs absorb the photon and its momentum is transferred, and excited electron emitted.

Explanation- the debroglie wavelength of the particle can be varying cyclically between two values ${\lambda }_1$ and ${\lambda }_2$ , if particle is moving in an elliptical orbit with origin as its focus.

Let v₁, v₂, be the speed of particle at A and B respectively and origin is at focus O. If ${\lambda }_1$ and ${\lambda }_2$ are the de-Broglie wavelengths associated with particle while moving at A and B

respectively. Then,

${\lambda }_1$ =h/mv₁

${\lambda }_2$  =h/mv₂

$\frac{{\lambda }_1}{{\lambda }_2}=\frac{v_2}{v_1}$

${\lambda }_1$ > ${\lambda }_2$

So v₂>v₁

By law of conservation of angular momentum, the particle moves faster when it is closer to

focus.

From figure, we note that origin O is closed to P than A

Explanation- energy spent to convert into water = mass $\times$ latent heat

= mL= 1000g $\times$ 80cal/g

= 80000cal

Energy of phtons used= nT $\times$ E=nT

So nTh $\times v$ =mL

T= mL/nhv

T $\propto$ 1/n where v is constant

T $\propto 1/v$ when n is fixed

T $\propto$ 1/nv

Explanation- ${\lambda }_e=\frac{h}{m_e{v}_e}$ = $\frac{h}{m_e\left(\frac{c}{100}\right)}=\frac{100h}{m_{e}c}$

E_e=1/2m_ev_e²

M_ev_e= $\sqrt[]{2E_e{m}_e}$

${\lambda }_e=\frac{h}{m_e{v}_e}=\frac{h}{\sqrt[]{2m_e{E}_e}}$

E_e= h²/2 $\lambda$ _e²m_e

For photon

E_p= hc/ ${\lambda }_p$ = hc/2 ${\lambda }_e$

$\frac{E_e}{E_p}=\frac{hc}{2{\lambda }_e}\times \frac{2{\lambda }_e^2{m}_e}{h^2}$ = 100

$\frac{E_e}{E_p}=\frac{1}{100}={10}^{-2}$

P_e=m_ev_e= m_{e $\times \frac{c}{100}$}

$\frac{P_e}{m_{e}c}=\frac{1}{100}={10}^{-2}$

This is a long answer type question as classified in NCERT Exemplar

Any ray entering at an angle I shall be guided along AC if the angle ray makes with the face AC (φ) is greater than the critical angle as per the principle of total internal reflection φ +r =900, therefore sinφ = cosr

Sinφ> $\frac{1}{\mu }$

Cosr> $\frac{1}{\mu }$

1-cos²r<1-1/ ${\mu }^2$

Sin²r<1-1/ ${\mu }^2$

Sin²r<1-1/ ${\mu }^2$

Sini = $\mu$ sinr

I= $\frac{\pi }{2}$

If that is greater than the critical then all other angle of incidence shall be more than the critical angle.

1< ${\mu }^2$ -1

$\mu$ > $\text{exception 25:}$

IIT Hyderabad accepts the IIT JAM entrance exam for admitting students to its MSc course. During the first round cutoff list, the closing ranks varied between 268 and 299 for the students belonging to the General AI quota. Considering the competitive cutoff rank of 268, M.Sc. in Physics turns out to be the toughest specialisation to get admission to. Tabulated below is the IIT JAM first round cutoff list 2025 of all the MSc specialsiations offered at IIT Hyderabad:

(i) As we know that power P_f=1/f=1/0.1+1/0.02=60D

By corrective lens the object distance at far pointP’_f=1/f’=1$\infty +$/1/0.02=50D

Total power P’_f=P_f+P_g

P_g=-10D

(ii) This power of accommodation is 4D for the normal eye then

4=P_n-P_f where P_n power of near point

So P_n= 64D

1/x_n+1/0.002=64 then x_n= 1/14=0.07m

(iii) P_n’=P_f’+4=54

After solving x_n’=4=0.25m

In the field of Engineering, Vidyavardhini's College of Engineering and Technology offers a full-time Bachelor of Engineering (BE). In total, there are 840 BE seats available at the college. These seats are further distributed among the BE specialisations offered at the college. The selection and eligibility criteria for admission against all these seats are common. The seats are allocated through the counselling (CAP) conducted by the Maharashtra CET cell (DTE). The mentioned number of seats is sourced from the official website of the college/ sanctioning body. It is still subject to change and hence, is indicative.
