Question

Magnetic field does not cause deflection in

• A. $\alpha$ rays
• B. ${\beta }^{+}$rays
• C. ${\beta }^{-}$ $rays$
• D. $\gamma$ $rays$

Answer 1

The correct option is D $\gamma$ $rays$

Gamma rays are highly energetic waves with no charge associated with them. Only charged particles get deflected in magnetic field, hence gamma rays are not deflected by magnetic field.
