NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT
In a single slit diffraction pattern, how is the angular width of central bright maximum changed when (i) the slit width is decreased. (ii) the distance bet
Apparent central core size of the observed image, often expressed as an angular image diameter that contains a given percentage of the available energy. Sometimes taken to be the full width at half maximum (FWHM) value of the intensity versus angular radius function. A complete definition of ima...
1a, the photons in each of the fringes are coherent and have the same spectrum and the interference visibility is thus dependent on the width of the spectrum; in Fig. 1b, however, the photons in the different fringes have different frequencies and the fringe visibility is dependent on the ...
With the rapid development of femtosecond lasers, the generation and application of optical vortices have been extended to the regime of intense-light-matter interaction. The characterization of the orbital angular momentum (OAM) of intense vortex pulses
d, Full-width of IC(t) at half-maximum. e, Time-integrated IC(t) over 0.0–0.7 ps versus dW from the data in a. Details of the error estimates are given in Methods. Feature (1) implies that IC(t) cannot arise from S transport. The reason is that the ISHE dominates the ...
To calculate the angular width of the central maxima in a single-slit diffraction pattern, we can follow these steps:Step 1: Understand the relationship for minima The condition for the minima in a single-slit diffraction patte
The lateral width of the focal spot at half maximum is 1.9 μm, and the experimental metasurface conversion efficiency is about 19%. The effect of spin–orbital conversion at a tight focus was theoretically considered in [15,16,17]. It was shown in [16] that the longitudinal component of...
