$\left(ii\right)$ exert pressure on an object

$\left(iii\right)$ have the same momentum

Of these statements

• A. $\left(i\right),\left(ii\right)$ and $\left(iii\right)$ are correct
• B. $\left(i\right)$ and $\left(ii\right)$ are correct
• C. $\left(ii\right)$ and $\left(iii\right)$ are correct
• D. $\left(i\right)$ and $\left(iii\right)$ are correct

Answer 1

The correct option is B

$\left(i\right)$ and $\left(ii\right)$ are correct

Definition of Electromagnetic Radiation

Electromagnetic radiation is defined as a form of energy that is produced by the movement of electrically charged particles.

Properties of Electromagnetic Radiation

$1$. Electromagnetic radiation exhibits particle-like properties that its energy occurs in quanta.

$2$. Electromagnetic radiation travel at the same speed.

$3$. Electromagnetic radiation varies in frequency and momentum.

$4$.Electromagnetic radiation exerts pressure on an object.

Therefore, Electromagnetic radiation has energy and exerts pressure.

Hence, the correct option is $\left(B\right)$
