Which outcome is observed at increasing gravitational redshift?

A)Light appears redder at the focus.
B)Wavelength decreases near blackholes.
C)Refraction reverses close to masses.
D)Particles exhibit increased interference effects.

💡 Explanation

Gravitational redshift increases the wavelength of light, a process caused by spacetime curvature due to an object's mass; therefore, light appears redder as energy decreases, rather than shifting toward blue or showing other spectral distortions in other gradients.
