Question

Statement-1: In YDSE, the spacing between any two successive points having intensity half of the maximum intensity is same. and Statement-2: The intensity on the screen in YDSE varies uniformly with distance from central maximum.

Options

G1 Physics · Accepted Answer

For equal slit intensities, I=Iₘₐₓcos²(φ/2). Half-maximum occurs for φ=(2n+1)π/2, so the half-intensity points are equally spaced: Statement 1 is true. Intensity varies as cos², not uniformly with distance, so Statement 2 is false. Option C.
