When a photon enters glass from air,which one of the following quantities does not change?

The momentum of a photon of light of frequency $f$ is . . . . . . .

If $c$ is the velocity of light in free space,the correct statements about photon among the following are:
$A$. The energy of a photon is $E=h v$.
$B$. The velocity of a photon is $c$.
$C$. The momentum of a photon,$p=\frac{h v}{c}$.
$D$. In a photon-electron collision,both total energy and total momentum are conserved.
$E$. Photon possesses positive charge.
Choose the correct answer from the options given below:

$A$ photon of wavelength $4400 \, \mathring{A}$ is passing through vacuum. The effective mass and momentum of the photon are respectively

The momentum of a photon of energy $1 \, MeV$ in $kg \, m/s$ will be:

Write the equation for the effective mass of a photon.
