The force acting on a particle of mass 1 kg moving in a circle of radius 0.5 m with speed 2 m/s is MCQ with Answer and Explanation

Explanation:
Minimum deviation δ_m for a prism: n = sin[(A + δ_m)/2] / sin(A/2), where A is prism angle, n refractive index. Thus δ_m depends on both A and n. Since n varies with wavelength (dispersion), δ_m also depends on wavelength, but the primary dependencies are A and n. Memory tip: 'δ_m increases with A and n; used to measure n'. This optics formula application is frequently tested in competitive exams. Always recall that minimum deviation occurs when ray passes symmetrically through prism, a key condition for derivation.

Explanation:
Polarized sunglasses block reflected glare (horizontal polarization). LCDs use liquid crystals to rotate polarization for pixel control. Memory tip: 'Polarization: sunglasses (glare reduction), LCDs (display technology)'. Optics application frequently tested in competitive exams.

Explanation:
Only transverse waves can be polarized.
