A student investigates the physical properties of alpha ( $α\alpha$ ), beta-minus ( $β−\beta^-$ ), beta-plus ( $β+\beta^+$ ), and gamma ( $γ\gamma$ ) emissions. Which statement regarding these radiations is correct?

Alpha ( $α\alpha$ ) particles have a higher penetrating power than beta-minus ( $β−\beta^-$ ) particles because they typically carry greater kinetic energy.

In a uniform magnetic field, beta-minus ( $β−\beta^-$ ) particles and beta-plus ( $β+\beta^+$ ) particles projected with the same velocity perpendicular to the field deflect in opposite directions with the same radius of curvature.

Gamma ( $γ\gamma$ ) radiation is deflected by strong electric fields because of the extremely high frequency of the electromagnetic waves.

Beta-minus ( $β−\beta^-$ ) particles have a greater range in air than gamma ( $γ\gamma$ ) rays because they have a much lower mass than alpha particles.
